Abstract
An integrated circuit having a transistor device and over-voltage protection circuitry. The transistor device is implemented in a technology having a specified operating-voltage range, the transistor device having gate, drain, source, and tub nodes, and the specified operating-voltage range having a specified maximum voltage. The over-voltage protection circuitry is adapted to apply gate and tub voltages to the gate and tub nodes, respectively. If at least one channel voltage applied to at least one of the drain and source nodes exceeds the specified maximum voltage, then the over-voltage protection circuitry controls at least one of the gate voltage and the tub voltage to inhibit one or more adverse effects to the transistor device.
