GENERAL DESCRIPTION  
The ADM8316/ADM8318/ADM8319/ADM8320/ADM8321/  
ADM8322 are supervisory circuits that monitor power supply  
voltage levels and code execution integrity in microprocessor-based  
systems. As well as 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 switch through a manual reset input.  
The six devices feature different combinations of watchdog  
input, manual reset input, and output stage configuration,  
as shown in Table 6.  
Each device is available in a choice of 27 reset threshold options  
ranging from 2.5 V to 5 V in 100 mV increments. There are also  
four reset timeout options of 1 ms, 20 ms, 140 ms, and 1120 ms  
(minimum) and four watchdog timeout options of 6.3 ms, 102 ms,  
1.6 sec, and 25.6 sec (typical). Not all device options are available  
as standard models. See the Ordering Guide for details.  
The ADM8316/ADM8318/ADM8319/ADM8320/ADM8321/  
ADM8322 are available in 5-lead SOT-23 packages and typically  
consume only 10 µA, making them suitable for use in low  
power, portable applications.
