    • A semiconductor device having a surge input detecting circuit is provided with the driving circuit for, for example, reversible motor. To prevent MOS power transistors constituting the power driving circuit from their destructive breakdowns (failures), when the surge input detecting circuit block detects the surge voltage input through the driving circuit which exceeds a predetermined voltage, namely, a maximum rated power supply voltage of the power driving circuit, the surge input detecting circuit outputs the signal to turn the MOS power transistors in off-states. These circuit elements are integrally mounted on a semiconductor chip. The surge input detecting circuit block detects such a surge input through a power supply terminal in terms of either of its voltage, its current, or the temperature rise in the semiconductor chip. The breakdown voltage per power transistor can be half the maximum rated power supply voltage. In addition, the surge input detecting circuit block and these power MOS transistors are fabricated into the same semiconductor chip.
    • 具有浪涌输入检测电路的半导体器件设置有用于例如可逆电动机的驱动电路。 为了防止构成电力驱动电路的MOS功率晶体管的破坏性故障(故障),当浪涌输入检测电路块检测到通过驱动电路输入的浪涌电压超过预定电压时,即最大额定电源电压 电源驱动电路,浪涌输入检测电路输出该信号,使MOS功率晶体管处于断开状态。 这些电路元件一体地安装在半导体芯片上。 浪涌输入​​检测电路块根据其电压,电流或半导体芯片的温度升高来检测通过电源端子的浪涌输入。 每个功率晶体管的击穿电压可以是最大额定电源电压的一半。 此外,浪涌输入检测电路块和这些功率MOS晶体管被制造成相同的半导体芯片。
