General Description
The G692/G693 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- pow-
ered circuits. The G692/G693 also provide a de-
bounced manual reset input.
These circuits perform a single function: they assert a
reset signal whenever the V
CC
supply voltage declines
below a preset threshold, keeping it asserted for at
least 140ms after V
CC
has risen above the reset
threshold. Reset thresholds suitable for operation with
a variety of supply voltages are available.
The G693L has an open-drain output stage, while the
G692 have push-pull outputs. The G693L’s open-drain
RESET
output requires a pull-up resistor that can be
connected to a voltage higher than V
CC
. The G692L
have an active-low RESET
output, while the G692H
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 1V.
Low supply current makes the G692/G693 ideal for
use in portable equipment. The G692/G693 are avail-
able in a 4-pin SOT143 packages.
