Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings 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.

The G698/G699 are microprocessor (P) supervisory circuits used to monitor the power supplies in P and digital systems. G698/G699 provide excellent circuit reliability and low cost and adjustments when used with +5V,+3.3V, +3.0V - powered circuits.

These circuits of G698/G699 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 G699L has an open-drain output stage, while the G698 have push-pull outputs. The G699L's open-drain RESET output requires a pull-up resistor that can be connected to a voltage higher than VCC. The G698L have an active-low RESET output, while the G698H 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.

Low supply current makes the G698/G699 ideal for use in portable equipment. The G698/G699 are available in 5-pin SOT23-5 packages.
