DRV8845 Quad H-Bridge Motor Driver Texas Instruments DRV8845 Quad H-Bridge Motor Driver is designed for various industrial applications. The device can drive up to two stepper motors or four brushed-DC motors. Each full-bridge output is rated up to 1.5A and 38V. The DRV8845 includes pulse width modulation (PWM) current regulators and 2-bit nonlinear DACs (digital-to-analog converters). This feature allows stepper motors to be controlled in full, half, and quarter steps, and DC motors in forward, reverse, and coast modes.
