GENERAL DESCRIPTION  
The ADM705/ADM706/ADM707/ADM708 microprocessor  
supervisory circuits are suitable for monitoring 5 V power  
supplies/batteries and can also monitor microprocessor activity.  
The ADM705 and ADM706 are identical except for the reset  
threshold monitor levels, which are 4.65 V and 4.40 V, respectively.  
The ADM707 and ADM708 provide a similar functionality to  
the ADM705 and ADM706 and only differ in that a watchdog  
timer function is not available. Instead, an active high reset  
output (RESET) is available as well as the active low reset output  
The ADM705/ADM706 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 1.60 seconds.  
RESET  
(
). The ADM707 and ADM708 are identical except for  
the reset threshold monitor levels, which are 4.65 V and 4.40 V,  
respectively.  
In addition, there is a 1.25 V threshold detector to warn of  
power-failures, to detect low battery conditions, or to monitor an  
additional power supply. An active low, debounced manual reset  
All parts are available in narrow 8-lead PDIP and 8-lead SOIC  
packages.
