LTC2951ITS8-2#TRMPBF

LTC2951-2 is a micropower, wide input voltage range pushbutton ON/OFF controller. The part contains a pushbutton input which controls the toggling of an open-drain enable output. The pushbutton turn OFF debounce time is externally programmable, while the turn ON debounce time is fixed at 128ms. A simple microprocessor interface allows for proper system house keeping prior to power down. Under system fault conditions, an adjustable KILL timeout delay ensures proper power-down. It is widely used in application such as portable instrumentation meters, blade servers, portable customer service PDA, desktop and notebook computers etc.
