Microprocessor Supervisory Circuits
General Description
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 CC down to 1V. The MAX691A/
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%.
