Product Overview

The LTC2954ITS8-2#PBF is a Pushbutton ON/OFF Controller that manages system power via a pushbutton interface. An enable output toggles system power while an interrupt output provides debounced pushbutton status. The interrupt output can be used in menu driven applications to request a system power-down. A power kill input allows a microprocessor or system to reset the enable output, effectively powering down the system. Independently adjustable on and off timers allow dependable pushbutton control of the enable output and resistance to accidental toggling of system power. The LTC2954 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 LTC2954 ideally suited for battery powered applications. Two versions of the part are available to accommodate either positive or negative enable polarities.
  • Simple interface allows graceful μP shutdown
  • High input voltage PB pin with internal pull-up resistor
  • ±10kV ESD HBM on PB input
  • Accurate 0.6V threshold on KILL comparator input
