Abstract
A load driver includes an active clamping circuit coupled between gate and source terminals of a power stage. The active clamping circuit serves to either pass through a gate drive voltage (provided by a gate driver) to the power stage in a PWM mode or to actively clamp the voltage between gate and source terminals of the power stage to enable fast decay recirculation in fast decay mode (when the load driver is configured for active clamping). A semi-active recirculation driver is coupled between ground and the output of the power stage. The semi-active recirculation driver serves to either provide a low impedance recirculation path in the PWM mode or to passively clamp the output voltage to provide for a fast decay recirculation path in fast decay mode (when the load driver is configured for passive clamping).
