GENERAL D ESCRIP TIO N

T he ADM8696/ADM8697 supervisory circuits offer 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 warning.

T he ADM8696/ADM8697 are available in 16-pin DIP and small

outline packages (including T SSOP) and provide the following

functions:

1. Power-On Reset output during power-up, power-down and

brownout conditions. T he RESET voltage threshold is

adjustable using an external voltage divider. T he RESET out-

put remains operational with V_CCas low as 1 V.

2. A Reset pulse if the optional watchdog timer has not been

toggled within specified time.

1.3V

3. Separate watchdog timeout and low line status outputs.

4. Adjustable reset and watchdog timeout periods.

T he 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_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.

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).
