GENERAL DESCRIPTION
The ADM706P/R/S/T and the ADM708R/S/T microprocessor
supervisory circuits are suitable for monitoring either 3 V or 3.3 V
power supplies.
The ADM706P/R/S/T provide the following functions:
1. Power-supply monitoring circuitry which generates a Reset
output during power-up, power-down and brownout condi-
tions. The reset output remains operational with V
CC
as low
as 1 V.
2. Independent watchdog monitoring circuitry which is acti-
vated if the watchdog input has not been toggled within
1.6 seconds.
3. A 1.25 V threshold detector for power fail warning, low bat-
tery detection, or to monitor an additional power supply.
4. An active low debounced manual reset input (
MR
).
The ADM706R, ADM706S, ADM706T are identical except for
the reset threshold monitor levels which are 2.63 V, 2.93 V, and
3.08 V respectively. The ADM706P is identical to the ADM706R
in that the reset threshold is 2.63 V. It differs only in that it has
an active high reset output.
The ADM708R/S/T provide the same functionality as the
ADM706R/S/T and only differ in that:
1.
A watchdog timer function is not available.
2.
An active high reset output (RESET) in addition to the
active low (
RESET
) output is available.
All parts are available in 8-lead DIP and narrow SOIC packages.
