The DRV8231DSGR is a motor controller and driver with a 33V H-bridge motor drive and current regulation manufactured by Texas Instruments. It is designed to minimize the amount of external circuitry required to control a three-phase motor, with a simple 3-phase PWM waveform, at a nominal 24V. It provides protection features, including over-current, over-temperature, and loss of phase. It includes a fast current regulation loop that reduces motor resonance, cogging and other audible noise. It also offers integrated fault diagnostics and built-in field-oriented control (FOC). The DRV8231DSGR is optimized for automotive applications, including motion, ignition, and motor control.
