GENERAL DESCRIPTION
The ADM690A/ADM692A/ADM802L/M/ADM805L/M
family of supervisory circuits offers 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, and power
failure warning.
The ADM690A/ADM692A/ADM802L/M/ADM805L/M are
available in 8-pin packages and provide:
1. Power-on reset output during power-up, power-down and
brownout conditions. The
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 devices.
3. A reset pulse if the optional watchdog timer has not been
toggled within 1.6 seconds.
4. A 1.25 V threshold detector for power fail warning, low battery
detection, or to monitor a power supply other than +5 V.
On the ADM690A/ADM802L/ADM805L the reset voltage
threshold is 4.65 V. On the ADM692A/ADM802M/
ADM805M, the reset voltage threshold is 4.40 V.
The ADM802L/ADM802M guarantee power fail accuracies to
±
2%.
The ADM805L/M provides an active high reset output, RESET
instead of
RESET.
The family of products is fabricated using an advanced epitaxial
CMOS process combining low power consumption and high
reliability.
RESET
assertion is guaranteed with V
CC
as low as 1 V.
They provide a pin-compatible upgrade for the MAX690A/
MAX692A/MAX802L/MAX802M/MAX805L
All parts are available in 8-pin DIP and SOIC packages. The
ADM690A is also available in a new space-saving microSOIC
package.
