LTC2955CDDB-2#TRMPBF

The LTC2955CDDB-2#TRMPBF is a Pushbutton On/Off Controller with automatic turn-on function. The micropower pushbutton controller manages system power by generating a clean enable output from the supply monitor input and the debounced pushbutton input. It features an interrupt output that notifies the system of a pushbutton or low supply event. When the system is ready, it may use the power kill input to shut off power. If the pushbutton remains pressed for more than the configurable turn-off duration, the system power is forced off. The supply input covers a wide range from 1.5 to 36V. The robust pushbutton input handles wide voltage swings of ±36V and ESD strikes to ±25kV (human body model) without latch-up or damage. A low 1.2µA supply current maximizes battery run time. Separate versions are available for positive or negative enable polarities.
