MAX691A General Description
The MAX691A/MAX693A/MAX800L/MAX800M microprocessor (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 chipenable propagation delay. Features include write protection of CMOS RAM or EEPROM, separate watchdog
outputs, backup-battery switchover, and a RESET output that is valid with VCC down to 1V. The MAX691A/ MAX800L have a 4.65V typical reset-threshold voltage, and the MAX693A/MAX800M's reset threshold is 4.4V typical. The MAX800L/MAX800M guarantee power-fail accuracies to ±2%.
