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- powered circuits. The G692/G693 also provide a de bounced manual reset input.
