µP Supervisor With Backup Battery Switchover, Watchdog Feature, Power Fail Warning, 4.65V Threshold Voltage, Active Low Reset And 100mA Output Current. Upgrade For ADM692 With Reduced Power Consumption

The ADM8690 ADM8692 and ADM8694 are available in 8-pin DIP packages and provide:
Power-on reset output during power-up, power-down and brownout conditions. The RESET output remains operational with VCC as low as 1 V. Battery backup switching for CMOS RAM, CMOS Microprocessor or other low power Logic A reset pulse if the optional watchdog Timer has not been toggled within a specified time. A 1.3 V threshold detector for power fail warning, low battery detection or to monitor a power supply other than +5 V. The ADM8691 ADM8693 and ADM8695 are available in 16-pin DIP and small outline packages (including TSSOP) and provide three additional functions:
Write protection of CMOS RAM or EEPROM Adjustable reset and watchdog timeout periods. Separate watchdog timeout, backup battery switchover, and low VCC status outputs.
