GENERAL D ESCRIP TIO N

T he ADM690–ADM695 family of supervisory circuits offers

complete single chip solutions for power supply monitoring and

battery control functions in microprocessor systems. T hese

functions include µP reset, backup battery switchover, watchdog

timer, CMOS RAM write protection, and power failure warn-

ing. T he complete family provides a variety of configurations to

satisfy most microprocessor system requirements.

3. A reset pulse if the optional watchdog timer has not been

toggled within a specified time.

1.3V

¹VOLTAGE DETECTOR = 4.65V (ADM691, ADM695)

4.40V (ADM693)

4. A 1.3 V threshold detector for power fail warning, low battery

detection, or to monitor a power supply other than +5 V.

T he 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_CCas 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.

T he 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_CCstatus outputs.
