µP Supervisor With Backup Battery Switchover, Watchdog Feature, Power Fail Warning, 4.4V Threshold Voltage, 100mA Output Current. Upgrade For ADM693 With Reduced Power Consumption And Faster Gating Of Chip Enable Signals

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.
