Texas Instruments High-Performance Analog TPIC44H01DA

The TPIC44H01 is a four-channel high-side pre-FET driver with serial and parallel input control for external NMOS power FETs, designed for low-frequency switching of resistive or inductive loads such as solenoids and incandescent bulbs. It is packaged in a 32-pin TSSOP (DA) case. Each channel features independent over-current, short-to-ground, and open-load detection with programmable deglitch timers, an over-voltage lockout circuit, and an asynchronous open-drain fault interrupt pin. The device supports a sleep mode for low quiescent current and can be cascaded via its SPI interface. An internal charge pump enables N-channel FET high-side drive with current-limited gate control. Operating temperature range is -40 to 125°C.
