Abstract
Described is a power multiplexer that alternately transmits zero, supply voltage, and a relatively high voltage to a common output node. The power multiplexer includes low-impedance voltage switches, at least one of which includes a well-voltage select circuit. The well-voltage select circuit adjusts the well bias on a power-switching transistor, and consequently protects the power-switching transistor from damage caused by gate breakdown and forwarding biasing of the well.
