This abstract first appeared for US patent application 18779646 titled 'SWITCHING CONTROL CIRCUIT
Original Abstract Submitted
A switching control circuit configured to control switching of a first switching device on a power supply side and a second switching device on a ground side, the first and second switching devices being configured to drive a load, the first switching device having an electrode on a low-potential side thereof. The switching control circuit includes: a first level shifter circuit including a first resistor and a first transistor; a driver circuit configured to drive the first switching device, in response to an output from the first level shifter circuit; a first switch connected in parallel with the first resistor; and an ON-OFF control circuit configured to turn on the first switch, in response to a voltage at the electrode becoming negative.
