Abstract:
An electronic device includes a load, a first switching element, a drive circuit, and a second switching element. The first switching element is disposed on a current path connected to the load. The drive circuit drives the first switching element by using a drive control signal which is based on a comparison result between a load signal and a reference signal. The load signal is obtained by converting, into a voltage, a current flowing through the current path. The reference signal serves as a reference of an operation of the first switching element. The second switching element is capable of switching the signal level of the drive control signal between a first level, at which the first switching element is switched off, and a second level, at which the first switching element is switched on.
