General Description

The G696/G697 are microprocessor (µP) supervisory
circuits used to monitor the power supplies in µP and
digital systems. They provide excellent circuit reliability
and low cost 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

CC

supply voltage declines
below a preset threshold, with hysteresis keeping it
asserted for time delay determined by externally pro­gramable time delay generator. after V

CC

has risen
above the reset threshold. Reset thresholds suitable
for operation with a variety of supply voltages are
available.

The G697L has an open-drain output stage, while the
G696 have push-pull outputs. The G697L’s open-drain

RESET output requires a pull-up resistor that can be

connected to a voltage higher than V

CC

. The G696L

have an active-low

RESET output, while the G696H
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

CC

down to 0.8V.

Low supply current makes the G696/G697 ideal for
use in portable equipment. The G696/G697 are avail­able in 5-pin SOT23-5 packages.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause p’ermanent damage to the device. These are stress rat-

ings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of

the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
