G697L293T1Uf SOT-23-5
Microprocessor Reset IC
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 VCC supply voltage declines
below a preset threshold, with hysteresis keeping it
asserted for time delay determined by externally programmable
time delay generator after VCC 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 VCC. 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 VCC,
and the outputs are guaranteed to be in the correct
logic state for VCC 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 or TSOT-23-5 packages.
