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.

Stresses beyond those listed under "Absolute Maximum Ratings" may cause p'ermanent damage to the device. These are stress rat- ings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
