The LM3722/LM3723/LM3724 microprocessor supervisory circuits monitor the power supplies in microprocessor and digital systems.

They provide a reset to the microprocessor during power-up, power-down, brown-out conditions, and manual reset.

The LM3722/LM3723/LM3724 asserts a reset signal whenever the supply decreases below the factory-programmed reset threshold for at least 100 ms.

n Precise monitoring of 2.5V, 3.3V, and 5V supply voltages n Fully specified over temperature Industrial:.
40˚C to +85˚C Extended:.
40˚C to +125˚C n 100 ms minimum Power-On Reset pulse width, 190 ms typical: Active-Low RESET Output (LM3722) Active-High RESET Output (LM3723) Active-Low RESET Open Drain Output (LM3724) n Guaranteed RESET Output valid for VCC ≥ 1V n Low Supply Current, 6µA typical n Power supply transient immunity n Compatible with MAX811/812.
