GENERAL DESCRIPTION  
The ADM8611/ADM8612/ADM8613/ADM8614/ADM8615  
are voltage supervisory circuits that monitor power supply voltage  
levels and code execution integrity in microprocessor-based  
systems. Apart from providing power-on reset signals, an on-  
chip watchdog timer can reset the microprocessor if it fails to  
strobe within a preset timeout period. A reset signal can also be  
asserted by an external push-button through a manual reset input.  
both the ADM8613 and ADM8614. A separate supply input  
allows the ADM8612 and ADM8615 to monitor 20 different  
low voltage levels from 0.5 V to 1.9 V. Not all device options are  
available as standard models. See the Ordering Guide for details.  
The ADM8611, ADM8612, ADM8613, and ADM8615 can  
reset on demand through the manual reset input. The watchdog  
function on the ADM8613, ADM8614, and ADM8615 monitors  
the heartbeat of the microprocessor through the WDI pin. The  
ADM8613 and ADM8614 have a watchdog disable input, which  
allows the user to disable the watchdog function, if required. The  
ADM8614 also has a watchdog timeout extension input, allowing  
the watchdog timeout to be extended from 1.6 sec to 100 sec.  
The ultralow power consumption of these devices makes them  
suitable for power efficiency sensitive systems, such as battery-  
powered portable devices and energy meters.  
The features of each member of the device family are shown in  
Table 9. Each device subdivides into submodels with differences  
in factory preset voltage monitoring threshold options. In the  
range of 2 V to 4.63 V, 10 options are available for the ADM8611.  
In the range of 2.32 V to 4.63 V, five options are available for  
The ADM8611/ADM8612/ADM8613/ADM8614/ADM8615  
are available in a 6-ball, 1.46 mm × 0.96 mm WLCSP. These  
devices are specified over the temperature range of −40°C to +85°C.
