The invention discloses an automobile distribution box and a power supply system. A first end and a second end of a power supply control chip are electrically connected with control ends of a first transistor and a second transistor respectively; the first ends of the first transistor and the second transistor are electrically connected with a main power supply line, the second end of the first transistor is electrically connected with a first load, and the second end of the second transistor is electrically connected with a second load; the main control chip is used for controlling the power supply control chip to enter a low-power-consumption working mode when the power supply current of the main power supply circuit is detected to be smaller than a first preset value; and the power supply control chip is used for controlling on-off of the first transistor and the second transistor in a low-power-consumption working mode, so that the main power supply line supplies power to the first load and the second load. According to the invention, the power supply control chip controls the on-off of the first transistor and the second transistor in the low-power-consumption mode, so that the power supply to the first load and the second load in the low-power-consumption mode is realized. And the requirements of the first load and the second load on low power consumption are met.
本发明公开了一种汽车配电盒和供电系统,供电控制芯片的第一端和第二端分别与第一晶体管和第二晶体管的控制端电连接;第一晶体管和第二晶体管的第一端均与主供电线电连接,第一晶体管的第二端与第一负载电连接,第二晶体管的第二端与第二负载电连接;主控芯片用于在检测到主供电线路的供电电流小于第一预设值时,控制供电控制芯片进入低功耗工作模式;供电控制芯片用于在低功耗工作模式下控制第一晶体管和第二晶体管的通断,以使主供电线为第一负载和第二负载供电。在本发明中通过供电控制芯片在低功耗模式下控制第一晶体管和第二晶体管的通断实现了在低功耗的模式下对第一负载和第二负载供电。满足了第一负载和第二负载对低功耗的要求。
