FEATURES
DESCRIPTION
The LTC
®
2950 is a micropower, wide input voltage range,
push button ON/OFF controller. The part contains a push
button 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 26V 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.
