LTC2950CTS8-1#TRPBF Datasheet PDF - Linear Technology

●The LTC2950CTS8-1#TRPBF is a micropower wide input voltage range Pushbutton ON/OFF Controller for use with blade servers. 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 internal KILL timer ensures proper power-down. The LTC2950 operates over a wide 2.7 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.
