The Miller clamp protection function is included to control the Miller current during power stage switching in half-bridge configurations. When the power switch is in the OFF state, the driver operates to avoid the induced turn-on phenomenon that may occur due to the CGD capacitance when the other switch in the same leg is being turned on. During the turn-off period, the switch gate is monitored via the CLAMP pin. The CLAMP switch is activated when gate voltage drops below the voltage threshold VCLAMPth, thus creating a low impedance path between the switch gate and the VL pin, see the figure below.
