ADI's High Accuracy Multivoltage Supervisor ICs Monitor Low Voltage Core Supplies for Peak Performance

Accurately monitoring the supply voltage of a microprocessor is critical to achieving the levels of performance and output required by today's sophisticated electrical equipment. To meet these needs, ADI's family of voltage monitors includes dual, triple, and quad variants that accommodate a wide range of voltage inputs.

The ADM6710 is a low voltage, high accuracy, microprocessor supervisory circuit capable of monitoring up to four system supply voltages. Should an input drop below its associated threshold, an active low output asserts. The output is open-drain with a weak internal pull-up to the monitored IN2 or VCC supply, typically 10 µA. Subsequent to all voltages rising above the selected threshold, the reset remains low for the reset timeout period (140 ms minimum).
