LTC2950IDDB-2#TRMPBF, Supervisory Circuits PB On/Off Cntr

LTC2950-2 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. It is widely used in application such as portable instrumentation meters, blade servers, portable customer service PDA, desktop and notebook computers etc. • Low supply current is 6µA• Wide operating voltage range is 2.7V to 26.4V• EN output allows circuit breaker control• Simple interface allows graceful µP shut down• High input voltage PB pin with internal pull up resistor• ±10KV ESD HBM on PB input• KILL input threshold voltage is 0.6V• Undervoltage lockout is 2.3V• Operating temperature is -40°C to 85°C• Packaging style is 8-lead plastic DFN
