LTC1154CS8#PBF

LTC1154 is a single 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. Included on chip is programmable overcurrent sensing. A time delay can be added to prevent false triggering on high inrush current loads. An active high shutdown input is also provided and interfaces directly to a standard PTC thermistor for thermal shutdown. An open-drain output is provided to report switch status to the µP. An active low enable input is provided to control multiple switches in banks. It is used in application such as laptop computer power switching, SCSI termination power switching, cellular telephone power management, battery charging and management, high side industrial and automotive switching, stepper motor and DC motor control etc.
