Abstract
The circuit and method translate a logic level input signal to signals at high voltage levels to drive a power device, such as a power MOSFET, while minimizing the power consumption. The circuit for driving the power device includes a low side gate driver, and a high side gate driver adjacent thereto. The high side gate drive includes a high side gate driver logic input, a high side gate driver output, a latch connected between the high side gate driver logic input and the high side gate driver output, and a control circuit receiving an output of the latch and controlling signals from the high side gate driver logic input to the latch based upon the output of the latch.
