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 to-  
gether for monitoring systems with fewer than six supply  
voltages, and the open drain RST output of two or more  
LTC2908 can be wired-OR together for monitoring sys-  
tems with more than six supply voltages. The common  
reset output remains low until all six inputs have been in  
compliance for 200ms.

Power Supply Glitch Immunity  
The LTC2908 features a tight 1.5% threshold accuracy  
over the entire operating temperature range and glitch  
immunity to ensure reliable reset operation without false  
triggering. Theopen-drainRSToutput state is guaranteed  
to be in the correct state as long as V1 and/or V2 is 0.5V  
or greater.
