A circuit provides means for driving a load under control of a plurality of signals including a drive timing signal which is given a maximum permissible duration by the circuit to prevent damage to the load, an operating signal, and an inhibit signal which prevents operation in case of excessively low power supply voltage. A power supply of opposite polarity is connected to the load so that the load rapidly dissipates its energy into said power supply at the time of turn-off of the drive circuit.
