The LTC2951ITS8-2#TRMPBF 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 housekeeping prior to powerdown. Under system fault conditions, an adjustable KILL timeout delay ensures proper power-down. The LTC2951 operates over a 2.7 to 26.4V input voltage range to accommodate a variety of input power supplies. Very low quiescent current (6μA typical) makes the LTC2951 ideally suited for battery powered applications. Two versions of the part are available to accommodate either positive or negative enable polarities.

• Adjustable pushbutton debounce and delay timers
• 6μA Low supply current
• Simple interface allows graceful μP shutdown
• High input voltage PB pin with internal pull-up resistor
• ±10kV ESD HBM on PB input
• Accurate 0.6V threshold on KILL comparator input
