G690/G691

General Description

The G690/G691 are microprocessor (µP) supervisory circuits used to monitor the power supplies in µP and digital systems. They provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with +5V, +3.3V, +3.0V- powered circuits.

These circuits perform a single function: they assert a reset signal whenever the V below a preset threshold, keeping it asserted for at least 140ms after V

threshold. Reset thresholds suitable for operation with a variety of supply voltages are available.

The G691L has an open-drain output stage, while the G690 have push-pull outputs. The G691L’s open-drain

RESET output requires a pull-up resistor that can be

connected to a voltage higher than V have an active-low

RESET output, while the G690H has an active-high RESET output. The reset comparator is designed to ignore fast transients on V and the outputs are guaranteed to be in the correct logic state for V

down to 1V.

Low supply current makes the G690/G691 ideal for use in portable equipment. The G690/G691 are available in 3-pin SOT-23 packages.

Detailed Description

A microprocessor’s (µP’s) reset input starts the µP in a known state. The G691L/G690L/G690H assert reset to prevent code-execution errors during power-up, power-down, or brownout conditions. They assert a reset signal whenever the V

has risen above the reset

threshold. The G691L uses an open-drain output, and the G690L/G690H have a push-pull output stage.

Applications Information

Negative-Going VCC Transients

In addition to issuing a reset to the µP during power-up, power-down, and brownout conditions, the G691L/G690H/G690L are relatively immune to shortduration negative-going V

Figure 1 shows typical transient duration vs. reset comparator overdrive, for which the G691L/G690H/ G690L do not generate a reset pulse. The graph was generated using a negative-going pulse applied to V starting 0.5V above the actual reset threshold and ending below it by the magnitude indicated (reset comparator overdrive). The graph indicates the maximum pulse width a negative-going V have without causing a reset pulse. As the magnitude of the transient increases (goes farther below the reset threshold), the maximum allowable pulse width decreases. Typically, for the G69_ _463 and G69_ _438,

transient that goes 100mV below the reset

a V

threshold and lasts 7µs or less will not cause a reset pulse. A 0.1µF bypass capacitor mounted as close as possible to the V immunity.

Ensuring a Valid Reset Output Down to VCC = 0 When V

falls below 1V, the G690 RESET output

no longer sinks current—it becomes an open circuit. Therefore, high-impedance CMOS logic inputs con-

nected to

RESET can drift to undetermined voltages. This presents no problem in most applications since most µP and other circuitry is inoperative with

below 1V. However, in applications where RESET must be valid down to 0V, adding a pull-down resistor

to RESET causes any stray leakage currents to flow to ground, holding

Interfacing to µPs with Bidirectional Reset Pins

Since the RESET output on the G691L is open drain, this device interfaces easily with µPs that have bidirectional reset pins, such as the Motorola 68HC11.

Connecting the µP supervisor’s rectly to the microcontroller’s (µC’s)

RESET output di-

RESET pin with a single pull-up resistor allows either device to assert reset (Figure 3).

G691L Open-Drain RESET Output Allows Use with Multiple Supplies

Generally, the pull-up connected to the G691L will connect to the supply voltage that is being monitored at the IC’s V

pin. However, some systems may use

the open-drain output to level-shift from the monitored supply to reset circuitry powered by some other supply (Figure 4). Note that as the G691L’s V

decreases

below 1V, so does the IC’s ability to sink current at

RESET. Also, with any pull-up, RESET will be pulled

high as

VCC decays toward 0. The voltage where this

occurs depends on the pull-up resistor value and the voltage to which it is connected.

Benefits of Highly Accurate Reset Threshold

Most µP supervisor ICs have reset threshold voltages between 5% and 10% below the value of nominal supply voltages. This ensures a reset will not occur within 5% of the nominal supply, but will occur when the supply is 10% below nominal.

Figure 4. G691L Open-Drain

lows Use with Multiple Supplies

RESET Output Al-

When using ICs rated at only the nominal supply ±5%, this leaves a zone of uncertainty where the supply is between 5% and 10% low, and where the reset may or may not be asserted.

The G69_ _463/G69_ _308 use highly accurate circuitry to ensure that reset is asserted close to the 5% limit, and long before the supply has declined to 10% below nominal.

DESCRIPTION

The TPS6220x devices are a family of high-efficiency synchronous step-down converters ideally suited for portable systems powered by 1-cell Li-Ion or 3-cell NiMH/NiCd batteries. The devices are also suitable to operate from a standard 3.3-V or 5-V voltage rail.

With an output voltage range of 6.0 V down to 0.7 V and up to 300 mA output current, the devices are ideal to power low voltage DSPs and processors used in PDAs, pocket PCs, and smart phones. Under nominal load current, the devices operate with a fixed switching frequency of typically 1 MHz. At light load currents, the part enters the power save mode operation; the switching frequency is reduced and the quiescent current is typically only 15 µA; therefore it achieves the highest efficiency over the entire load current range. The TPS6220x needs only three small external components. Together with the tiny SOT23 package, a minimum system solution size can be achieved. An advanced fast response voltage mode control scheme achieves superior line and load regulation with small ceramic input and output capacitors.

DETAILED DESCRIPTION

OPERATION

The TPS6220x is a synchronous step-down converter operating with typically 1MHz fixed frequency pulse width modulation (PWM) at moderate to heavy load currents and in power save mode operating with pulse frequency modulation (PFM) at light load currents.

During PWM operation the converter uses a unique fast response, voltage mode, controller scheme with input voltage feed forward. This achieves good line and load regulation and allows the use of small ceramic input and output capacitors. At the beginning of each clock cycle initiated by the clock signal (S), the P-channel MOSFET switch is turned on, and the inductor current ramps up until the comparator trips and the control logic turns off the switch. The current limit comparator also turns off the switch in case the current limit of the P-channel switch is exceeded. Then the N-channel rectifier switch is turned on and the inductor current ramps down. The next cycle is initiated by the clock signal again turning off the N-channel rectifier and turning on the P-channel switch.

DETAILED DESCRIPTION (continued)

The GM amplifier and input voltage determines the rise time of the Sawtooth generator; therefore any change in input voltage or output voltage directly controls the duty cycle of the converter. This gives a very good line and load transient regulation.

POWER SAVE MODE OPERATION

As the load current decreases, the converter enters the power save mode operation. During power save mode, the converter operates with reduced switching frequency in PFM mode and with a minimum quiescent current to maintain high efficiency.

Two conditions allow the converter to enter the power save mode operation. One is when the converter detects the discontinuous conduction mode. The other is when the peak switch current in the P-channel switch goes below the skip current limit. The typical skip current limit can be calculated as

During the power save mode the output voltage is monitored with the comparator by the thresholds comp low and comp high. As the output voltage falls below the comp low threshold set to typically 0.8% above Vout nominal, the P-channel switch turns on. The P-channel switch is turned off as the peak switch current is reached. The typical peak switch current can be calculated:

The N-channel rectifier is turned on and the inductor current ramps down. As the inductor current approaches zero the N-channel rectifier is turned off and the P-channel switch is turned on again, starting the next pulse. The converter continues these pulses until the comp high threshold (set to typically 1.6% above Vout nominal) is reached. The converter enters a sleep mode, reducing the quiescent current to a minimum. The converter wakes up again as the output voltage falls below the comp low threshold again. This control method reduces the quiescent current typically to 15 µA and reduces the switching frequency to a minimum, thereby achieving the high converter efficiency. Setting the skip current thresholds to typically 0.8% and 1.6% above the nominal output voltage at light load current results in a dynamic output voltage achieving lower absolute voltage drops during heavy load transient changes. This allows the converter to operate with a small output capacitor of just 10 µF and still have a low absolute voltage drop during heavy load transient changes. Refer to Figure 2 for detailed operation of the power save mode.

Figure 2. Power Save Mode Thresholds and Dynamic Voltage Positioning

The converter enters the fixed frequency PWM mode again as soon as the output voltage falls below the comp low 2 threshold.

DETAILED DESCRIPTION (continued) DYNAMIC VOLTAGE POSITIONING

As described in the power save mode operation sections and as detailed in Figure 2 , the output voltage is typically 0.8% above the nominal output voltage at light load currents, as the device is in power save mode. This gives additional headroom for the voltage drop during a load transient from light load to full load. During a load transient from full load to light load, the voltage overshoot is also minimized due to active regulation turning on the N-channel rectifier switch.

SOFT START

The TPS6220x has an internal soft start circuit that limits the inrush current during start-up. This prevents possible voltage drops of the input voltage in case a battery or a high impedance power source is connected to the input of the TPS6220x.

The soft start is implemented as a digital circuit increasing the switch current in steps of typically 60 mA,120 mA, 240 mA and then the typical switch current limit of 480 mA. Therefore the start-up time mainly depends on the output capacitor and load current. Typical start-up time with 10 µF output capacitor and 200 mA load current is 800 µs.

LOW DROPOUT OPERATION 100% DUTY CYCLE

The TPS6220x offers a low input to output voltage difference, while still maintaining operation with the 100% duty cycle mode. In this mode, the P-channel switch is constantly turned on. This is particularly useful in battery powered applications to achieve longest operation time by taking full advantage of the whole battery voltage range. The minimum input voltage to maintain regulation, depending on the load current and output voltage, can be calculated as

ENABLE

Pulling the enable low forces the part into shutdown, with a shutdown quiescent current of typically 0.1 µA. In this mode, the P-channel switch and N-channel rectifier are turned off, the internal resistor feedback divider is disconnected, and the whole device is in shutdown mode. If an output voltage, which could be an external voltage source or super cap, is present during shutdown, the reverse leakage current is specified under electrical characteristics. For proper operation the enable pin must be terminated and must not be left floating.

Pulling the enable high starts up the TPS6220x with the soft start as previously described.

UNDERVOLTAGE LOCKOUT

The undervoltage lockout circuit prevents the device from misoperation at low input voltages. It prevents the converter from turning on the switch or rectifier MOSFET under undefined conditions.

APPLICATION INFORMATION

ADJUSTABLE OUTPUT VOLTAGE VERSION

When the adjustable output voltage version TPS62200 is used, the output voltage is set by the external resistor divider. See Figure 16 .

The output voltage is calculated as

• R1 + R2 ≤ 1 MΩ and internal reference voltage V(ref)typ = 0.5 V R1 + R2 should not be greater than 1 MΩ for reasons of stability. To keep the operating quiescent current to a

minimum, the feedback resistor divider should have high impedance with R1+R2 ≤ 1 MΩ. Because of the high impedance and the low reference voltage of V minimized. Using a capacitive divider C1 and C2 across the feedback resistors minimizes the noise at the feedback without degrading the line or load transient performance.

C1 and C2 should be selected as

= 0.5 V, the noise on the feedback pin (FB) needs to be

ref

• R1 = upper resistor of voltage divider

• C1 = upper capacitor of voltage divider

For C1 a value should be chosen that comes closest to the calculated result.

• R2 = lower resistor of voltage divider

• C2 = lower capacitor of voltage divider

For C2 the selected capacitor value should always be selected larger than the calculated result. For example, in Figure 16 for C2, 100 pF are selected for a calculated result of C2 = 86.17 pF.

If quiescent current is not a key design parameter, C1 and C2 can be omitted, and a low-impedance feedback divider must be used with R1+R2 <100 kΩ. This design reduces the noise available on the feedback pin (FB) as well, but increases the overall quiescent current during operation.

INDUCTOR SELECTION

The TPS6220x device is optimized to operate with a typical inductor value of 10 µH. For high efficiencies, the inductor should have a low dc resistance to minimize conduction losses. Although the

inductor core material has less effect on efficiency than its dc resistance, an appropriate inductor core material must be used.

APPLICATION INFORMATION (continued)

The inductor value determines the inductor ripple current. The larger the inductor value, the smaller the inductor ripple current, and the lower the conduction losses of the converter. On the other hand, larger inductor values cause a slower load transient response. Usually the inductor ripple current, as calculated below, is around 20% of the average output current.

In order to avoid saturation of the inductor, the inductor should be rated at least for the maximum output current of the converter plus the inductor ripple current that is calculated as

The highest inductor current occurs at maximum Vin. A more conservative approach is to select the inductor current rating just for the maximum switch current of

670 mA. Refer to Table 1 for inductor recommendations.

INPUT CAPACITOR SELECTION

Because the buck converter has a pulsating input current, a low ESR input capacitor is required. This results in the best input voltage filtering and minimizing the interference with other circuits caused by high input voltage spikes. Also the input capacitor must be sufficiently large to stabilize the input voltage during heavy load transients. For good input voltage filtering, usually a 4.7 µF input capacitor is sufficient. It can be increased without any limit for better input-voltage filtering. If ceramic output capacitors are used, the capacitor RMS ripple current rating always meets the application requirements.

Ceramic capacitors show a good performance because of the low ESR value, and they are less sensitive against voltage transients and spikes compared to tantalum capacitors.

Place the input capacitor as close as possible to the input pin of the device for best performance (refer to Table 2 for recommended components).

OUTPUT CAPACITOR SELECTION

The advanced fast response voltage mode control scheme of the TPS6220x allows the use of tiny ceramic capacitors with a value of 10 µF without having large output voltage under and overshoots during heavy load transients.

Ceramic capacitors with low ESR values have the lowest output voltage ripple and are therefore recommended. If required, tantalum capacitors may be used as well (refer to Table 2 for recommended components).

At nominal load current the device operates in PWM mode and the overall output voltage ripple is the sum of the voltage spike caused by the output capacitor ESR plus the voltage ripple caused by charging and discharging the output capacitor:

where the highest output voltage ripple occurs at the highest input voltage Vin. At light load currents, the device operates in power save mode, and the output voltage ripple is independent of

the output capacitor value. The output voltage ripple is set by the internal comparator thresholds. The typical output voltage ripple is 1% of the output voltage Vo.

LAYOUT CONSIDERATIONS

For all switching power supplies, the layout is an important step in the design, especially at high peak currents and switching frequencies. If the layout is not carefully done, the regulator shows stability problems as well as EMI problems.

Therefore use wide and short traces for the main current paths, as indicated in bold in Figure 17 . The input capacitor, as well as the inductor and output capacitor, should be placed as close as possible to the IC pins

The feedback resistor network must be routed away from the inductor and switch node to minimize noise and magnetic interference. To further minimize noise from coupling into the feedback network and feedback pin, the ground plane or ground traces must be used for shielding. This becomes very important especially at high switching frequencies of 1 MHz.
