G697

Global Mixed-mode Technology Inc. G696/G697 Microprocessor Reset IC Features Precision Monitoring of +3V, +3.3V, and +5V Power-Supply Voltages General Description The G696/G697 are microprocessor (µP) supervisory circuits used to monitor the power supplies in µP and digital systems. They provide excellent circuit reliability and low cost and adjustments when used with +5V, +3.3V, +3.0V- powered circuits. These circuits perform a single function: they assert a reset signal whenever the VCC supply voltage declines below a preset threshold, with hysteresis keeping it asserted for time delay determined by externally programmable time delay generator after VCC has risen above the reset threshold. Reset thresholds suitable for operation with a variety of supply voltages are available. The G697L has an open-drain output stage, while the G696 have push-pull outputs. The G697L’s open-drain RESET output requires a pull-up resistor that can be connected to a voltage higher than VCC. The G696L have an active-low RESET output, while the G696H has an active-high RESET output. The reset comparator is designed to ignore fast transients on VCC, and the outputs are guaranteed to be in the correct logic state for VCC down to 0.8V.
