Abstract

PURPOSE: To prevent a boosted output level from being reversed to a power supply voltage side by providing an MOSFET flowing a leakage current between gates of an output MOSFET and its driving MOSFET and a common potential point.
CONSTITUTION: The leakage current circuit (MOSFET) Q12 operated in response to an output timing signal ϕout to be boosted is provided between a gate of an MOSFET of a power supply voltage VCC side constituting a drive circuit (MOSFET) Q8, Q9 and an output circuit (MOSFET) Q10, Q11. Through the constitution above, when the said output timing signal ϕout is boosted, the power supply voltage side MOSFETQ10 is almost turned off, the MOSFETQ10 is operated reversely by the boosted level of the output timing signal and the bootstrap circuit preventing the boosted level from being leaked to the power supply voltage side.
