LTC2908  
Precision  
Six Input Supply Monitor  
FEATURES  
DESCRIPTION  
The LTC®2908 is a six input supply monitor for systems  
requiring a precise and compact monitoring solution  
for multiple supply voltages. The inputs can be shorted  
together for monitoring systems with fewer than six  
supply voltages, and the open drain RST output of two or  
more LTC2908s can be wired-OR together for monitoring  
systemswithmorethansixsupplyvoltages.Thecommon  
reset output remains low until all six inputs have been in  
compliance for 200ms.
