Abstract
PURPOSE:To execute a turning-off at a high speed by connecting a capacitor for charging to the output side of a charging pump for driving a gate of an N-MOS transistor for an output and opening and closing the section of the gate with a switch. CONSTITUTION:By an ON signal from a terminal 51, a charging pump 2 is operated by a control signal 101 from a control circuit 1, a prescribed voltage is outputted and a capacitor 4 is charged. A signal 103 from the circuit 1 goes to L, an N-MOS transistor(TR) 6 is turned off, a switch circuit 3 is turned on, gate capacities 7 and 8 are charged, and an N-MOSFET 9 goes to an action condition. When an OFF signal is outputted from the circuit 1, a charging pump is turned off, the signal 103 goes to H, an N-MOSTR 6 is turned on, a switch 3 is turned off and the N-MOSFET 9 goes to a non-action condition. Next, when it is transferred to ON, an action condition is obtained in a very short time by the charge of the capacitor 4. Thus, the turning-off is executed at a high speed.
