GENERAL DESCRIPTION
The ADM696/ADM697 supervisory circuits offer complete
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 ADM696/ADM697 are available in 16-pin DIP and small
outline packages and provide the following functions:
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
output 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 time-out and low line status outputs.
4. Adjustable reset and watchdog timeout periods.
5. A 1.3 V threshold detector for power fail warning, low bat-
tery 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 (ADM696).
7. Write protection of CMOS RAM or EEPROM (ADM697).
The ADM696/ADM697 is fabricated using an advanced epitaxial
CMOS process combining low power consumption (5 mW),
extremely fast Chip Enable gating (5 ns) and high reliability.
RESET
assertion is guaranteed with V
CC
as low as 1 V. In
addition, the power switching circuitry is designed for minimal
voltage drop thereby permitting increased output current drive
of up to 100 mA without the need for an external pass transistor.
