ADVANCE INFORMATION
To protect the ext. FET gate and the internal gate drive circuit the charge sharing circuit of the gate driver features an over voltage clamp. If the voltage goes above VTH(BST_OV) the linear regulator from the boot strap charge sharing sinks a current from HBx to SWx as long as the voltage is above the threshold.
