Please note the following spec sheet covers more than one MAXIM product.
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 type 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/MAX800Ms’ reset threshold is 4.4V typical. The MAX800L/MAX800M guarantee power-fail accuracies to ±2%.
* Critical µP Power Monitoring
200ms Power-OK/Reset Timeout Period
1µA Standby Current, 30µA Operating Current
On-Board Gating of Chip-Enable Signals,10ns max Delay
MaxCapâ„¢ or SuperCapâ„¢ Compatible
Guaranteed RESET Assertion to VCC = +1V
Voltage Monitor for Power-Fail or Low-Battery Warning
Power-Fail Accuracy Guaranteed to ±2% (MAX800L/M)
