Abstract
A power switch includes two power FETs connected back-to-back in series at a common source node and a common gate node and a resistor connected between the common source node and the common gate node. The switch further includes a current source and a single-control switch connected to the current source and to the gate node for switching the current source to the gates of the two power FETs.
