Description
LTC2955
Pushbutton On/Off Controller
with Automatic Turn-On
Demonstration circuit 1836A-A and 1836A-B feature the
LTC
®
2955-1 and LTC2995-2, respectively. The LTC2955 is
a micropower, pushbutton on/off controller that manages
system power by generating a clean enable output from
the supply monitor input and the debounced pushbut-
ton input. It features an interrupt output that notifies the
system of a pushbutton event or low level at the ON pin.

When the system receives an
INT
signal, it may use the
power kill input to shut off power. If the pushbutton remains
pressed for more than the configurable turn-off duration
(3s or 32ms), the system power is forced off.
