MAX697 Datasheet (Maxim) - Microprocessor Supervisory Circuits

MAX697, Microprocessor Supervisory Circuits

The MAX696/MAX697 supervisory circuits reduce the complexity and number of components required for power-supply monitoring and battery-control functions in microprocessor (μP) systems.

These include μP reset and backup-battery switchover, watchdog timer, CMOS RAM write protection, and power-failure
