LTC1156 - Quad High Side Micropower MOSFET Driver with Internal Charge Pump

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.
