GENERAL DESCRIPTION  
POWER FAIL  
INPUT (PFI)  
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.  
POWER FAIL  
OUTPUT (PFO)  
1.25V  
*VOLTAGE REFERENCE = 2.63V (R), 2.93V (S), 3.08V (T)  
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 VCC as low  
as 1 V.  
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. Independent watchdog monitoring circuitry which is acti-  
vated if the watchdog input has not been toggled within  
1.6 seconds.  
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.  
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.
