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.
