Two-state, bilateral, single-pole, double-throw, half-bridge power-switching apparatus capable of high speed, high current switching over a duty factor range of zero percent to 100% includes a single-wire connector to a source of switching signals, a first FET whose gate is connected to the single-wire connector, and a second FET having its gate connected to the drain of the first FET and its source connected to the drain of the first FET through a device for preventing, in part, cross-current from the first FET to the second FET and for permitting the gate voltage on the second FET to be raised sufficiently high to turn on the second FET. The apparatus also includes a system for delivering on/off signals to the second FET and for holding the second FET on or off in response to switching signals having a duty factor in the range of zero percent to 100%.
