LTC2954
Pushbutton On/Off
Controller with ВµP Interrupt
FEATURES DESCRIPTION n The LTCВ®2954 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. n Adjustable Power On/Off Timers
