4.5 Improved Precision in Motor Control

The DRV8376 comes with optimized switching to minimize the dead time to less than 150ns and propagation delay to less than 100ns. The low dead time, propagation delay and propagation delay mismatch are critical in minimizing the current distortion in motor to get precise and quiet motor control. In HVAC applications, precise positioning of the valves requires precise motor control for best cooling/heating experience.
