LTC2950IDDB-1#TRMPBF

LINEAR TECHNOLOGY  LTC2950IDDB-1#TRMPBF  芯片, 按钮控制器, 8DFN

The 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 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.
