battery control functions in microprocessor systems. These
functions include μ P reset, backup battery switchover, watchdog
timer, CMOS RAM write protection, and power failure warn-
ing. The complete family provides a variety of configurations to
satisfy most microprocessor system requirements.

The ADM691, ADM693 and ADM695 are available in 16-pin
DIP and small outline packages and provide three additional
functions.
1. Write protection of CMOS RAM or EEPROM.
2. Adjustable reset and watchdog timeout periods.
3. Separate watchdog timeout, backup battery switchover, and
low V CC status outputs.
REV. A
Information furnished by Analog Devices is believed to be accurate and
reliable. However, no responsibility is assumed by Analog Devices for its
use, nor for any infringements of patents or other rights of third parties
which may result from its use. No license is granted by implication or
otherwise under any patent or patent rights of Analog Devices.
The ADM690–ADM695 family is fabricated using an advanced
epitaxial CMOS process combining low power consumption
(5 mW), extremely fast Chip Enable gating (5 ns) and high reli-
ability. 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.
