Abstract
A high voltage driver includes a high-side output transistor circuit, a differential to single-ended (D2SE) converter connected to a gate of the high-side output transistor circuit, wherein the D2SE is supplied by a first and a second supply voltage, and a high voltage translator connected to the D2SE converter. The D2SE converter and the translator circuit are used to clamp a voltage at the gate of the high-side transistor circuit to be the first supply voltage less the second supply voltage.
