The invention provides a power supply circuit, a chip, a vehicle-mounted control device and a motor vehicle, and the power supply circuit comprises a constant power supply module, a non-normal power supply module, a switch main control module, and an inverse proportion amplification circuit. The control end of the constant power supply module is connected with a power supply, the input end of the constant power supply module is connected with the power supply and the input end of the inverse proportion amplification circuit, and the output end of the constant power supply module is connected with a load; the control end of the non-common power supply module is connected with the output end of the inverse proportion amplification circuit, the input end of the non-common power supply module is connected with the power supply, and the output end of the non-common power supply module is connected with the load; the switch master control module controls the connection state of the power supply and the constant power supply module and/or the non-normal power supply module. The running state of the power supply circuit can be changed according to the current change caused by the change of the working state of the load, so that the energy consumption of the load is effectively reduced under the condition of ensuring that the load needs to maintain the power-on state all the time, and the energy consumption of the whole vehicle is further reduced.
