Description
General part information
LTC2950 Series
The LTC2950 is a micropower, wide input voltage range, pushbutton ON/OFF controller. The part contains a pushbutton 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 microprocessor interface to allow for proper system housekeeping prior to power down. Under system fault conditions, an internalKILLtimer 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 accommodate either positive or negative enable polarities. The parts are available in either 8-lead 3mm × 2mm DFN or ThinSOT packages.ApplicationsPortable Instrumentation MetersBlade ServersPortable Customer Service PDADesktop and Notebook Computers
