Texas Instruments DRV8x Integrated Motor Drivers

Texas Instruments DRV8x Integrated Motor Drivers

Texas Instruments DRV8x motor drivers are intended to drive an electromagnetic machine, such as a brushed or brushless motor, stepper motor, or other electromechanical actuator. The TI DRV8x family of integrated motor drivers enables designers to quickly and easily spin their motors, reducing time to market and greatly simplifying design. By integrating the gate drive circuitry, sense amps, protection, FETS, industry standard control interfaces, and drive algorithms, the design complexity, board space, and time to spin a motor have all be greatly reduced. With on-chip protection including overcurrent, thermal, shoot-through, and undervoltage, the DRV8x family is robust, reliable, and fully protected.
