The invention discloses an automobile electromechanical switch circuit, which is characterized by comprising an active load circuit, the active load circuit comprises a first diode connected between acomplementary data line and a first control transistor, and a second diode connected between the data line and a second control transistor, wherein the common pulse-width-modulated switching unit and/or the common freewheeling unit is a semiconductor switch or a semiconductor switch with an integrated diode, and the resistance of the second load device is changed in response to the level of the complementary data line, the active load circuit also includes a first control transistor configured to generate a first control signal in response to a voltage level of the data line, and a second control transistor configured to generate a second control signal in response to a voltage level of the complementary data line. The active load circuit may also include an operation control transistor connected between the common node and the second supply voltage, wherein the operation control transistor is turned on or off in response to the enable signal.

    本发明公开了一种汽车机电开关电路,其特征在于,包括有源负载电路,所述有源负载电路包括连接在互补数据线与第一控制晶体管之间的第一二极管,以及连接在数据线与第二控制晶体,共用的脉宽调制的开关单元和/或共用的空转单元为半导体开关或带有集成二极管的半导体开关,其中,第二负载器件的电阻响应互补数据线的电平而改变,有源负载电路还包括被配置用来响应数据线的电压电平来产生第一控制信号的第一控制晶体管,以及被配置用来响应互补数据线的电压电平来产生第二控制信号的第二控制晶体管。有源负载电路也可以包括连接在公共节点与第二电源电压之间的操作控制晶体管,其中,操作控制晶体管响应使能信号而导通或截止。
