    • According to one embodiment, a switching circuit includes a high-side switch, a rectifier, and a driver. The high-side switch is connected between a high potential terminal and an output terminal. The rectifier is connected between the output terminal and a low potential terminal, forward direction of the rectifier is a direction from the low potential terminal to the output terminal. The driver is connected between the high potential terminal and the output terminal. The driver switches a high-side switch ON based on a high-side control signal. The driver switches the high-side switch OFF when a first short detector detects shorts of the output terminal with the low potential terminal after a first period longer than a backward recovery time of the rectifier until the high-side control signal changing.
    • 根据一个实施例,开关电路包括高侧开关,整流器和驱动器。 高侧开关连接在高电位端子和输出端子之间。 整流器连接在输出端子和低电位端子之间,整流器的正向是从低电位端子到输出端子的方向。 驱动器连接在高电位端子和输出端子之间。 驱动器根据高端控制信号切换高侧开关。 当第一短路检测器在比整流器的向后恢复时间长的第一周期之后,检测到具有低电位端子的输出端子的短路,直到高侧控制信号改变为止,驱动器将高侧开关切换到OFF。
