The LTC1156 quad High side gate driver allows using low
cost N-channel FETs for high side switching applications.
An internal charge pump boosts the gate drive voltage
above the positive rail, fully enhancing an N-channel MOS
switch with no external components. Micropower opera-
tion, with 16µA standby current and 95µA operating
current, allows use in virtually all systems with maximum
efficiency.
Included on chip is independent over-current sensing to
provide automatic shutdown in case of short circuits. A
time delay can be added to the current sense to prevent
false triggering on high in-rush current loads.
The LTC1156 operates off of a 4.5V to 18V supply and is
well suited for battery-powered applications, particularly
where micropower “sleep” operation is required.
The LTC1156 is available in both 16-pin DIP and 16-pin
SOL packages.
