General Description

The MAX690A/MAX692A/MAX802L/MAX802M/MAX805L reduce the complexity and number of components required for power-supply monitoring and batterycontrol functions in microprocessor (μP) systems.

They significantly improve system reliability and accuracy compared to separate ICs or discrete components.

These parts provide four functions: 1) A reset output during power-up, power-down, and brownout conditions.
