The TPIC44H01 is a four channel high-side pre-FET driver which provides serial or parallel input interface to control four external NMOS power FETs. It is designed for use in low frequency switching applications for resistive or inductive loads, including solenoids and incandescent bulbs.

Each channel has over-current, short-to-ground, and open-load detection that is flagged through the FLT\ pin and distinguished through the serial interface. Over-current thresholds are set through the V_{(PK_x)} and V_(COMP1-4) pins. Short-to-ground and open-load thresholds are set internally to approximately 2.5 V. The AR_ENBL pin is used to define the operation of the device during a fault condition, allowing the outputs to either latch off or to enter a low duty cycle, auto-retry mode.
