The MAX691A/MAX693A/MAX800L/MAX800M micro-

processor (µP) supervisory circuits are pin-compatible

upgrades to the MAX691, MAX693, and MAX695. They

improve performance with 30µA supply current, 200ms

typ reset active delay on power-up, and 6ns chip-

enable propagation delay. Features include write pro-

tection of CMOS RAM or EEPROM, separate watchdog

outputs, backup-battery switchover, and a RESET out-

put that is valid with V

MAX800L have a 4.65V typical reset-threshold voltage,

and the MAX693A/MAX800Ms’ reset threshold is 4.4V

typical. The MAX800L/MAX800M guarantee power-fail

accuracies to ±2%.
