Patent ID: 7443200

Claim:
A circuit, comprising: an H-bridge arrangement of field effect transistors, including a pair of high-side transistors connected to a power supply node, the H-bridge having a pair of output nodes, each output node disposed on an opposite side of the H-bridge; a first pair of input terminals, each of the first pair of input terminals capacitively coupled to a gate electrode of a respective one of the high-side transistors; and a pair of voltage dividers, wherein one side of each voltage divider is coupled to the power supply node, an intermediate node of each voltage divider is coupled to the power supply node through at least one circuit element, and the other side of each voltage divider is cross-coupled to the output node of the opposite side of the H-bridge; wherein the at least one circuit element coupled to a first intermediate node of a first one of the pair of voltage dividers is operable to change the voltage at the first intermediate node so as to provide voltage tracking with the power supply node, and the at least one circuit element coupled to a second intermediate node of a second one of the pair of voltage dividers is operable to change the voltage at the second intermediate node so as to provide voltage tracking with the power supply node.
