Abstract: An adaptive gate driver for a driving a power MOSFET to switch is disclosed. The adaptive gate driver includes a load sense circuit to sense a current through the power MOSFET. A controller coupled to the load sense circuit compares the sensed current to a threshold to determine if the load on the power MOSFET is a normal load or a heavy load. Based on the comparison, the controller controls the gate driver to drive the power MOSFET with a first strength level when a normal load determined and at second strength level when a heavy load is determined. The driving strength in the heavy-load condition is lower than the normal-load condition and by lowering the driving strength of the gate driver during the heavy-load condition a voltage across the power MOSFET may be prevented from exceeding a threshold related to a breakdown condition during a switching period.
