SWITCHING CONTROL CIRCUIT
First Claim
1. A switching control circuit for driving a first switching element and a second switching element composing a half-bridge circuit comprising:
- a first output terminal that outputs a first drive signal to the first switching element based on a first pulse signal and a second pulse signal;
a second output terminal that outputs a second drive signal to the second switching element based on a first pulse signal and a second pulse signal; and
a protecting circuit that outputs the first drive signal and the second drive signal that turn OFF at least one of the first switching element and the second switching element upon inputting the first pulse signal and the second pulse signal.

Abstract
It is possible to reliably prevent two switching elements comprising a half-bridge circuit from turning ON simultaneously even when two pulse signals allowing both the two switching elements to turn ON are input thereto.
A first drive signal is allowed to be output from a first output terminal 4 to a P-type MOSFET 10 based on a first pulse signal and a second pulse signal, and a second drive signal is allowed to be output from a second output terminal 5 to an N-type MOSFET 11 that operates as a second switching element based on the first pulse signal and the second pulse signal, and a protecting circuit 20 is configured to allow at least one of the P-type MOSFET 10 and the N-type MOSFET 11 to turn OFF.
