single chip solutions for power supply monitoring and battery
control functions in microprocessor systems. These functions
include μ P reset, backup battery switchover, watchdog timer,
CMOS RAM write protection and power failure warning.
The ADM8696/ADM8697 are available in 16-pin DIP and small
outline packages (including TSSOP) and provide the following

1. Power-On Reset output during power-up, power-down and
brownout conditions. The RESET voltage threshold is
adjustable using an external voltage divider. The RESET out-
put remains operational with V CC as low as 1 V.
2. A Reset pulse if the optional watchdog timer has not been
toggled 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 battery
detection or to monitor a power supply other than V CC .
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).

Information furnished by Analog Devices is believed to be accurate and
reliable. However, no responsibility is assumed by Analog Devices for its

which may result from its use. No license is granted by implication or
The ADM8696/ADM8697 is fabricated using an advanced
epitaxial CMOS process combining low power consumption
(0.7 mW), extremely fast Chip Enable gating (2 ns) and high re-
liability. RESET assertion is guaranteed with V CC as low as 1 V.
In addition, the power switching circuitry is designed for mini-
mal voltage drop thereby permitting increased output current drive
of up to 100 mA without the need for an external pass transistor.
