    • A load drive device for driving an inductive load by PWM controlling a switching element includes synchronization control unit, a synchronization signal input terminal, and a synchronization signal output terminal. The synchronization control unit outputs the PWM signal to the switching element. The synchronization control unit receives a synchronization signal through the input terminal from an exterior. The synchronization control unit outputs the synchronization signal through the output terminal to an exterior. When the synchronization control unit does not receive the synchronization signal, the synchronization control unit outputs the synchronization signal such that a first switching period of the PWM signal is prevented from overlapping with a second switching period of a PWM signal of an external device. When the synchronization control unit receives the synchronization signal, the synchronization control unit generates the PWM signal based on the synchronization signal.
    • 用于通过PWM控制开关元件驱动感性负载的负载驱动装置包括同步控制单元,同步信号输入端子和同步信号输出端子。 同步控制单元将PWM信号输出到开关元件。 同步控制单元从外部通过输入端子接收同步信号。 同步控制单元通过输出端子输出同步信号到外部。 当同步控制单元没有接收同步信号时,同步控制单元输出同步信号,使得防止PWM信号的第一开关周期与外部设备的PWM信号的第二开关周期重叠。 当同步控制单元接收同步信号时,同步控制单元基于同步信号产生PWM信号。
