Upgrade for ADM696/ADM697, MAX696/MAX697

ADM8696ARW-REEL GENERAL DESCRIPTION

The ADM8696/ADM8697 supervisory circuits offer completesingle chip solutions for power supply monitoring and batterycontrol functions in microprocessor systems. These functionsinclude µP reset, backup battery switchover, watchdog timer,CMOS RAM write protection and power failure warning.The ADM8696/ADM8697 are available in 16-pin DIP and smalloutline packages (including TSSOP) and provide the followingfunctions:1. Power-On Reset output during power-up, power-down andbrownout conditions. The RESET voltage threshold isadjustable using an external voltage divider. The RESET out-put remains operational with VCC as low as 1 V.2. A Reset pulse if the optional watchdog timer has not beentoggled within specified time.3. Separate watchdog timeout and low line status outputs.4. Adjustable reset and watchdog timeout periods.5. A 1.3 V threshold detector for power fail warning, low batterydetection or to monitor a power supply other than VCC.6. Battery backup switching for CMOS RAM, CMOS micro-processor or other low power logic (ADM8696).7. Write protection of CMOS RAM or EEPROM (ADM8697).©1997-2010 Analog Devices, Inc.
