The LTC1156CSW#PBF is a quad high-side Gate Driver allows using 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. Micro-power operation 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 4.5 to 18V supply and is well suited for battery-powered applications, particularly where micro-power sleep operation is required.
