Abstract
A driver circuit for a power transistor. The driver circuit allows for robust turn-off of the power transistor, and for reduced power losses when the power transistor transitions back on. The driver circuit controls what voltage is applied to the gate terminal of the power transistor. The driver circuit prevents unintended turn-on of the power transistor by applying a negative voltage to the gate terminal of the power transistor when transitioning off. The driver circuit allows for reduced power losses when transitioning back on by allowing the gate terminal of the power transistor to increase from the negative voltage to a less negative voltage before applying a positive voltage to turn on the power transistor.
