The LTC2950ITS8-1#TRMPBF is a micropower pushbutton ON/OFF Controller with wide input voltage range. 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.
- Adjustable pushbutton on/off timers
- Low supply current (6μA)
- EN output allows DC/DC converter control
- Simple interface allows graceful μP shut down
- High input voltage PB pin with internal pull up resistor
- ±10kV ESD HBM on PB input
- Accurate 0.6V threshold on KILL comparator input
