G696/G697
Microprocessor Reset IC
Features
Precision Monitoring of +3V, +3.3V, and +5V
Power-Supply Voltages
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 pro-
grammable 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 com-
parator 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.
