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
below a preset threshold, with hysteresis keeping it
asserted for time delay determined by externally pro-
grammable time delay generator after V
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
connected to a voltage higher than V
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
and the outputs are guaranteed to be in the correct
logic state for V
Low supply current makes the G696/G697 ideal for
use in portable equipment. The G696/G697 are avail-
able in 5-pin SOT23-5 or TSOT-23-5 packages.
