Abstract
PURPOSE:To shorten the turning-off time without reducing the output of an output transistor TR by adding a CMOS inverter circuit to a gate driving circuit and providing a reverse current stopping TR for the purpose of preventing the electric charge stored in the gate of the output TR from flowing out even at the time of setting the potential of an output terminal to a value higher than the supply voltage. CONSTITUTION:The trigger signal to operate a boosting circuit 2 is inputted to a trigger terminal 5 of the boosting circuit 2 simultaneously with setting of an input terminal 18 of first and second CMOS inverter circuits 13 and 17 to the low level. Since the gate of an output TR 1 is charged together with the boosting circuit 2, the gate potential quickly rises, and the turning-on time of an output TR 16 is shortened. When the gate potential of the output TR 1 exceeds the supply voltage (VDD) by harging, source-drain junctions of N- channel TRs 13 and 14 are reverse biased. Therefore, the gate potential of the output TR 1 is sufficiently higher than the supply voltage, and the turning-on resistance of the output TR 1 is sufficiently reduced; and thus, the source output of a large current is obtained through an output terminal 6.
