  • Publication number: 20160241227
    Abstract: A driver circuit 101 is connected to a control terminal of a semiconductor switching element 1. The driver circuit 101 includes an input circuit 3 connected to an input terminal 50, and an output control circuit 4 connected to the input circuit 3. A pulse signal output from the output control circuit 4 is input to a dead time adjustment circuit 13. The dead time adjustment circuit 13 includes a delay circuit which can delay the rising edge and the falling edge of the pulse signal output from the output control circuit 4 on the basis of signals from temperature analog output circuits 11 and 12. An output from the dead time adjustment circuit 13 is input to the drive circuit 5. The drive circuit 5 outputs a drive signal to an output terminal 51 of the driver circuit 101.

  • Patent number: 8692589
    Abstract: A driving circuit outputs an output voltage as a driving signal to the gate of a semiconductor element based on a control signal given from an input circuit. The output voltage is at “H” (ON level) if it is determined by a power supply voltage VCC, and is at “L” (OFF level) if it is determined by a ground voltage GND. A reference power supply section includes a series connection of resistors. The reference power supply section obtains a voltage determined by dividing a potential difference between the power supply voltage VCC and the ground voltage GND by a predetermined dividing ratio (resistance ratio between the resistors) as a reference voltage. A buffer circuit applies an output voltage as a reference signal determined by the reference voltage to the source of the semiconductor element.
