General Description
The G680/G681 are microprocessor (µP) supervisory circuits used to monitor the power supplies in µP and digital systems. High- and Low- voltage thresholds can be adjusted independently, allowing for wide hysteresis. Voltage detection thresholds are accurate to 2%.
These circuits perform a single function: they assert a reset...
