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 VCC supply voltage declines
below a preset threshold, keeping it asserted for at
least 140ms after VCC 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 VCC. 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 VCC,
and the outputs are guaranteed to be in the correct
logic state for VCC 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.

Typical Operating Characteristics
(VCC = full range, TA = -40°C to +105°C, unless otherwise noted. Typical values are at TA = +25°C, VCC = 5V
for 463/438/400 versions, VCC= 3.3V for 308/293 versions, and VCC = 3V for 263 version.)
