Push Button On/Off
Controller
The LTC2951 is a micropower, wide input voltage range
push button ON/OFF controller. The part contains a push
button input which controls the toggling of an open drain
enable output. The push button turn OFF debounce time
is externally programmable, while the turn ON debounce
time is xed at 128ms. A simple microprocessor interface
allows for proper system housekeeping prior to power
down. Under system fault conditions, an adjustable KILL
timeout delay ensures proper power down.
The LTC2951 operates over a 2.7V to 26V input voltage
range to accommodate a variety of input power supplies.
Very low quiescent current (6A typical) makes the
LTC2951 ideally suited for battery powered applications.
Two versions of the part are available to accommodate
either positive or negative enable polarities. The parts
are available in 8-pin 3mm × 2mm DFN and ThinSOT
packages.
