Abstract
A voltage driver for supplying a supply voltage includes multiple PMOS transistors, multiple NMOS transistors, a pad, impedance divider circuits, NMOS clampers, PMOS clampers, a gate protection circuit, and a bulk protection circuit. A maximum of the supply voltage is N times a maximum of the drain-source voltage of each transistor. The pad is configured to receive a voltage signal for dynamically controlling gates of a subset of the NMOS transistors and a subset of the PMOS transistors. The impedance divider circuits are configured to generate voltage signals. The NMOS clampers and PMOS clampers are configured to receive reference voltages and limited voltage signals to generate output. The gate protection circuit are between outputs of the clampers and gates of the transistors. The bulk protection circuit is between bodies of the transistors and the impedance divider circuit.
