1. An overvoltage detector for an RF switch comprising circuitry having a detector output that couples to a controller, a body voltage input that couples to a charge pump, and a body voltage output that couples to a body terminal of the RF switch, wherein the circuitry is configured to detect an overvoltage across the RF switch by monitoring body leakage current flowing between the body voltage input and the body voltage output, and upon detecting body leakage current over a predetermined current level, generate an overvoltage signal at the detector output to indicate the overvoltage across the RF switch.
