General Description
The G686/G687 microprocessor (µP) supervisory circuits monitor system voltages in µP and digital systems. They provide excellent circuit reliability at low cost by eliminating external components.
Since the sense pin is separated from power supply, it allows the IC to monitor added power supply. Using the IC with the s.
