LTC1156 Quad High Side Micropower MOSFET Driver

LTC1156 Quad High Side Micropower MOSFET Driver with Internal Charge Pump DESCRIPTIO 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 operation, with 16µA standby current and 95µA operating current, allows use in virtually all systems with maximum efficiency. Included on chip.
