GENERAL DESCRIPTION  
The ADM706P/ADM706R/ADM706S/ADM706T and the  
ADM708R/ADM708S/ADM708T microprocessor supervisory  
circuits are suitable for monitoring either 3 V or 3.3 V power  
supplies.  
The ADM706R, ADM706S, and 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 ADM706P/ADM706R/ADM706S/ADM706T provide  
power-supply monitoring circuitry that generate a reset output  
during power-up, power-down, and brownout conditions. The  
reset output remains operational with VCC as low as 1 V.  
Independent watchdog monitoring circuitry is also provided.  
This is activated if the watchdog input has not been toggled  
within 1.6 seconds.  
The ADM708R/ADM708S/ADM708T provide similar functio-  
nality as the ADM706R/ADM706S/ADM706T and only differ  
in that a watchdog timer function is not available. Instead, an  
active high reset output (RESET) is provided in addition to the  
RESET  
active low ( ) output.  
All parts are available in narrow 8-lead PDIP and 8-lead SOIC  
packages.  
In addition, there is a 1.25 V threshold detector for power-fail  
warning, low battery detection, or to monitor an additional power  
MR  
supply. An active low debounced  
input is also included.
