LTC1255CS8#PBF

LTC1255 is a dual high-side driver allows using low cost N-channel FETs for high-side industrial and automotive 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. Low power operation, with 12µA standby current, allows use in virtually all systems with maximum efficiency. Included on-chip is independent overcurrent 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. It is used in application such as solenoid drivers, DC motor drivers, stepper motor drivers, lamp drivers/dimmers, relay drivers, low frequency H-bridge, P-channel switch replacement etc.
