    • A circuit for protecting a load from an overvoltage can be integrated together with the load on the same chip by an MOS transistor manufacture process. This overvoltage protecting circuit is composed of a surge protection circuit, an overvoltage detecting circuit and a switching circuit. The surge protection circuit including two MOS transistors operates so that a surge voltage applied to a power supply receiving terminal is clamped by virtue of the source-drain breakdown voltage of the two MOS transistors, thereby absorbing the surge energy. The overvoltage detecting circuit including two MOS transistors operates so that a DC voltage supplied from the surge protection circuit is monitored with the source-drain voltage of the two MOS transistors taken as a reference voltage, thereby detecting an overvoltage. An overvoltage detection output brings an MOS transistor of the switching circuit into a turned-off condition to protect the load.
    • 可以通过MOS晶体管制造工艺将用于保护负载的过电压的电路与负载集成在同一芯片上。 该过电压保护电路由浪涌保护电路,过电压检测电路和开关电路构成。 包括两个MOS晶体管的浪涌保护电路工作,借助于两个MOS晶体管的源极 - 漏极击穿电压来钳位施加到电源接收端的浪涌电压,从而吸收浪涌能量。 包括两个MOS晶体管的过电压检测电路进行工作,从而以两个MOS晶体管的源极 - 漏极电压作为参考电压来监视从浪涌保护电路提供的直流电压,从而检测过电压。 过电压检测输出使开关电路的MOS晶体管成为关断状态,以保护负载。

    • A master unit sends a start signal to a slave unit. When receiving the start signal from the master unit, the slave unit sends, to the master unit, a synchronization field that is a data train (pulse signal) indicative of a transfer clock with which the slave unit is able to perform transferring and receiving operations. The master unit sends, to the slave unit, command data in accordance with the transfer clock indicated by the synchronization field sent from the slave unit. In response to the command data sent from the master unit, the slave unit sends, to the master unit, response data in accordance with the transfer clock indicated by the synchronization field. Thus, in a communication system employing a serial data transferring apparatus of the present invention, the master unit establishes the synchronization for the data transfer, while the slave unit is free from a burden of establishing the synchronization for the data transfer. A serial data transferring apparatus is realized which can simplify the structure of the slave unit, cut the total cost, and reduce noise.
    • 主单元向从单元发送启动信号。 当从主单元接收到起始信号时,从单元向主单元发送同步字段,该同步字段是指示从单元能够执行传送和接收操作的传送时钟的数据串(脉冲信号) 。 主单元根据从从单元发送的同步字段指示的传送时钟向从属单元发送命令数据。 响应于从主单元发送的命令数据,从单元根据由同步字段指示的传送时钟向主单元发送响应数据。 因此,在采用本发明的串行数据传送装置的通信系统中,主单元建立用于数据传送的同步,而从单元没有建立用于数据传送的同步的负担。 实现了串行数据传送装置,其可以简化从单元的结构,降低总成本并降低噪声。
