GENERAL DESCRIPTION  
The ADM6316/ADM6317/ADM6318/ADM6319/ADM6320/  
ADM6321/ADM6322 are supervisory circuits which 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  
Each part is available in a choice of 26 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  
(min) and four watchdog timeout options of 6.3 ms, 102 ms,  
1600 ms, and 25.6s (typ).  
microprocessor if it fails to strobe within a preset timeout  
period. A reset signal can also be asserted by means of an  
external push-button, through a manual reset input. The seven  
parts feature different combinations of watchdog input, manual  
reset input and output stage configuration, as shown in Table 1.  
The ADM6316-ADM6322 are available in 5-lead SOT-23  
packages and typically consume only 3 µA, making them  
suitable for use in low power portable applications.
