GENERAL DESCRIPTION
The ADM691A/ADM693A/ADM800L/ADM800M family of
supervisory circuits offers complete single chip solutions for
power supply monitoring and battery control functions in
microprocessor systems. These functions include μP reset,
backup-battery switchover, watchdog timer, CMOS RAM write
protection, and power-failure warning. The family of products
provides an upgrade for the MAX691A/93A/800M family of
products.
All parts are available in 16-pin DIP and SO packages. The
ADM691A is also available in a space-saving TSSOP package.
The following functionality is provided:Power-on reset output during power-up, power-down and
brownout conditions. The circuitry remains operational with
VCC as low as 1 V.Battery backup switching for CMOS RAM, CMOS micro-
processor or other low power logic.A reset pulse if the optional watchdog timer has not been
toggled within a specified time.A 1.25 V threshold detector for power fail warning, low bat-
tery detection, or to monitor a power supply other than +5 V.

the device at these or any other conditions above those listed in the operational
sections of this specification is not implied. Exposure to absolute maximum ratings
for extended periods of time may affect device reliability.
