Product Overview

The LTC2954CTS8-1#TRMPBF is a micropower pushbutton ON/OFF Controller with µP interrupt 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.
  • Adjustable pushbutton on/off timers
  • Low supply current (6µA)
  • Low leakage 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
ESD sensitive device, take proper precaution while handling the device.
