DRV8809 Overview
The DRV8809/DRV8810 provides an integrated motor driver solution. The chip has four H-bridges internally and is configurable to eight different modes of bination motor driver control. The output driver block for each H-bridge consists of N-channel power MOSFETs configured as full Hbridges to drive the motor windings.
