Abstract
A semiconductor device includes a first and a second output transistor on a high and a low side respectively, a first terminal connected to the connection node between the first and second output transistors, and a second terminal configured to be connected via a bootstrap capacitor to the first terminal. The first output transistor is driven based on a voltage between the first and second terminals. A switching circuit is provided between a terminal fed with a predetermined control supply voltage and the second terminal. The switching circuit includes a first and a second switching element, which are N-channel MOSFETs connected in series. According to the voltage at the first terminal, the first and second switching elements are turned on or off.
