Product Overview

The LTC2953CDD-1#PBF is a Pushbutton On/Off Controller with voltage monitoring. The pushbutton controller 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. The LTC2953 also features input and output power supply monitors. An uncommitted power fail comparator provides real time input monitor information, while a de-glitched under-voltage lockout comparator gracefully initiates a system power-down. The under-voltage lockout comparator prevents the system from powering from a low power supply. The adjustable supply monitor input is compared against an accurate internal 0.5V reference. The reset output remains low until the supply monitor input has been in compliance for 200ms. The LTC2953 operates over a wide 2.7 to 27V input voltage range and draws only 14μA of current.
  • Pushbutton control of system power

  • Adjustable power-down timer
  • Low leakage EN output allows DC/DC converter control
  • Simple interface allows orderly system power-up and power-down
  • ±1.5% Threshold tolerance
  • ±10kV ESD HBM on PB\ input
