Abstract
A semiconductor device includes, a high side drive circuit for controlling the high side power device and including a circuit load, a low side drive circuit for controlling the low side power device, a VCC terminal connected to the low side drive circuit and for supplying a VCC potential to the low side drive circuit, the VCC potential serving as a power supply potential to the low side drive circuit, a bootstrap diode connected at its anode to the VCC terminal and at its cathode to the high side drive circuit and used to produce a VB potential serving as a power supply potential to the high side drive circuit, and means for turning off the circuit load before the VB potential becomes lower than the VCC potential.
