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