T he ADM8690–ADM8695 family of supervisory circuits offers
complete single chip solutions for power supply monitoring and
battery control functions in microprocessor systems. T hese
functions include
μ
P reset, backup battery switchover, watchdog
timer, CMOS RAM write protection and power failure warning.
T he complete family provides a variety of configurations to sat-
isfy most microprocessor system requirements.
T he ADM8690, ADM8692 and ADM8694 are available in
8-pin DIP packages and provide:
1. Power-on reset output during power-up, power-down and
brownout conditions. T he
RESET
output remains opera-
tional with V
CC
as low as 1 V.
2. Battery backup switching for CMOS RAM, CMOS
microprocessor or other low power logic.
3. A reset pulse if the optional watchdog timer has not been
toggled within a specified time.
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 ADM8691, ADM8693 and ADM8695 are available in
16-pin DIP and small outline packages (including T SSOP) 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.
T he ADM8690–ADM8695 family is fabricated using an ad-
vanced epitaxial CMOS process combining low power con-
sumption (0.7 mW), extremely fast Chip Enable gating (3 ns)
and high reliability.
RESET
assertion is guaranteed with V
CC
as
low as 1 V. In addition, the power switching circuitry is de-
signed for minimal voltage drop thereby permitting increased
output current drive of up to 100 mA without the need of an
external pass transistor.
