Overview
MAX690A/MAX692A/ MAX802L/MAX802M/ MAX805L
Microprocessor Supervisory Circuits
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.
2) Battery-backup switching for CMOS RAM, CMOS μP, or other low-power logic.
3) A reset pulse if the optional watchdog timer has not been toggled within 1.
6s.
4) A 1.
