Six Input Supply Monitor

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
systems with more than six supply voltages. The common
reset output remains low until all six inputs have been in
compliance for 200ms.
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.
The open-drain
RST
output state is guaranteed to be in the
correct state as long as V1 and/or V2 is 0.5V or greater.
The LTC2908 also features adjustable inputs with a nominal
threshold level at 0.5V. This product provides a precise,
space-conscious, micropower and general purpose solu-
tion for any kind of system requiring supply monitors.
