The ADM1085/ADM1086/ADM1087/ADM1088 are simple sequencing circuits that provide a time delay between the enabling of voltage regulators and/or dc-dc converters at powerup in multiple supply systems. When the output voltage of the first power module reaches a preset threshold, a time delay is initiated before an enable signal allows subsequent regulators to power up. Any number of these devices can be cascaded with regulators to allow sequencing of multiple power supplies.

Threshold levels can be set with a pair of external resistors in a v

oltage divider configuration. With appropriate resistor values,

the threshold can be adjusted to monitor voltages as low as 0.6 V.

The ADM1086 and ADM1088 have push-pull output stages,

ith active high (ENOUT) and active low (

w

ENOUT

) logic

outputs, respectively. The ADM1085 has an active-high (ENOUT) logic output; the ADM1087 has an active-low (

ENOUT

) output. Both the ADM1085 and ADM1087 have

open-drain output stages that can be pulled up to voltage levels as high as 22 V through an external resistor. This level-shifting property ensures compatibility with enable input logic levels of different regulators and converters.

The Simple Sequencers are specified over the extended

ESD CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although this product features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.

CIRCUIT INFORMATION

TIMING CHARACTERISTICS AND TRUTH TABLES

The enable outputs of the ADM1085/ADM1086/ADM1087/ ADM1088 are related to the V AND function. The enable output is asserted only if the enable input is asserted and the voltage at V the time delay elapsed. Tab le 5 and Tabl e 6 show the enable

utput logic states for different V

o when the capacitor delay has elapsed. The timing diagrams in Figure 18 and Figure 19 give a graphical representation of how

Figure 20 shows the internal circuitry used to generate the time delay on the enable output. A 250 nA current source charges a small internal parasitic capacitance (C voltage reaches 1.2 V, the enable output is asserted. The time taken for the capacitor to reach 1.2 V, in addition to the propagation delay of the comparator, constitutes the enable timeout, which is typically 35 μs.

To minimize the delay between V and the enable output deasserting, an NMOS transistor is connected in parallel with C

OPEN-DRAIN AND PUSH-PULL OUTPUTS

The ADM1085 and ADM1087 have open-drain output stages that require an external pull-up resistor to provide a logic high voltage level. The geometry of the NMOS transistor enables the output to be pulled up to voltage levels as high as 22 V.

The ADM1086 and ADM1088 have push-pull (CMOS) output stages that require no external components to drive other logic circuits. An internal PMOS pull-up transistor provides the logic high voltage level.

APPLICATION INFORMATION

SEQUENCING CIRCUITS

The ADM1085/ADM1086/ADM1087/ADM1088 are compatible with voltage regulators and dc-to-dc converters that have active high or active low enable or shutdown inputs, with a choice of open-drain or push-pull output stages.

Figure 23 to

M1087/ADM1088 simple sequencers can be used in

AD multiple-supply systems, depending on which regulators are used and which output stage is preferred.

In Figure 23, three ADM1085s are used to sequence four s

determine the time delays between enabling of the 3.3 V, 2.5 V,

1.8 V, and 1.2 V supplies. Because the dc-to-dc converters and ADM1085s are connected in a cascade, and the output of any converter is dependent on that of the previous one, an external controller can disable all four supplies simultaneously by disabling the first dc-to-dc converter in the chain.

For power-down sequencing, an external controller dictates w

DUAL LOFO SEQUENCING

A power sequencing solution for a portable device, such as a PDA, is shown in Figure 27. This solution requires that the

roprocessor power supply turn on before the LCD display

mic turns on, and that the LCD display power-down before the microprocessor powers down. In other words, the last power supply to turn on is the first one to turn off (LOFO).

SIMULTANEOUS ENABLING

The enable output can drive multiple enable or shutdown regulator inputs simultaneously.

An RC network connects the battery and the

input of the

SD

ADP3333 voltage regulator. This causes power-up and powerdown transients to appear at the

input when the battery is

SD

connected and disconnected. The 3.3 V microprocessor supply turns on quickly on power-up and turns off slowly on powerdown. This is due to two factors: Capacitor C1 charges up to 9 V on power-up and charges down from 9 V on power-down, and the

pin has logic high and logic low input levels of 2 V

SD

and 0.4 V.

For the display power sequencing, the ADM1085 is equipped w

ith Capacitor C2 to create the delay between the microprocessor and display power turning on. When the system is powered down, the ADM1085 turns off the display power immediately, while the 3.3 V regulator waits for C1 to discharge to 0.4 V before switching off.

POWER GOOD SIGNAL DELAYS

Sometimes sequencing is performed by asserting power good signals when the voltage regulators are already on, rather than sequencing the power supplies directly. In these scenarios, a simple sequencer IC can provide variable delays so that enabling separate circuit blocks can be staggered in time.

For example, in a notebook PC application, a dedicated

ocomputer asserts a power good signal for North Bridge™

micr and South Bridge™ ICs. The ADM1086 delays the South Bridge signal, so that it is enabled after the North Bridge.

QUAD-SUPPLY POWER GOOD INDICATOR

The enable output of the Simple Sequencers is equivalent to an AND function of V the voltage at V (ENIN) is high as well. Although ENIN is a digital input, it can tolerate voltages as high as 22 V and can detect if a supply is present. Therefore, a simple sequencer can monitor two supplies and assert what can be interpreted as a power good signal when both supplies are present. The outputs of two ADM1085s can be wire-AND’ed together to make a quadsupply power good indicator.

SEQUENCING WITH FET SWITCHES

The open-drain outputs of the ADM1085 and ADM1087 can drive external FET transistors that can switch on power supply rails. All that is needed is a pull-up resistor to a voltage source that is high enough to turn on the FET.
