The LTC
®
2950 is a micropower, wide input voltage range, 
pushbutton ON/OFF controller. The part contains a pushbut-
ton input with independently programmable ON and OFF 
debounce times that control the toggling of an open drain 
enable output. The part also contains a simple micropro-
cessor interface to allow for proper system housekeeping 
prior to power down. Under system fault conditions, an 
internal KILL timer ensures proper power down.
The LTC2950 operates over a wide 2.7V to 26.4V input 
voltage range to accommodate a wide variety of input 
power supplies. Very low quiescent current (6µA typical) 
makes the LTC2950 ideally suited for battery powered 
applications. Two versions of the part are available to ac-
commodate either positive or negative enable polarities. 
The parts are available in either 8-lead 3mm 
× 2mm DFN 
or ThinSOT packages.
