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
supply voltage declines
CC
below a preset threshold, keeping it asserted for at
least 140ms after V
has risen above the reset
CC
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
. The G690L
CC
has an active-high RESET output. The reset comparator is designed to ignore fast transients on V
CC
and the outputs are guaranteed to be in the correct
logic state for V
down to 1V.
CC
Low supply current makes the G690/G691 ideal for
use in portable equipment. The G690/G691 are available in 3-pin SOT89 or SOT23 or SC70 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
supply voltage declines
CC
below a preset threshold, keeping it asserted for at
least 140ms after V
has risen above the reset
CC
threshold. The G691L uses an open-drain output, and
the G690L/G690H have a push-pull output stage.
Connect a pull-up resistor on the G691L’s

put to any supply between 0 and 5.5V.

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,
a V
transient that goes 100mV below the reset
CC
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
CC
no longer sinks current—it becomes an open circuit.

This presents no problem in most applications since

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.

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

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
CC
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
CC
below 1V, so does the IC’s ability to sink current at
RESET . Also, with any pull-up, RESET will be pulled

high as
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.
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.
