Control circuit for reducing power consumption of electronic product and control method

Abstract

The invention provides a control circuit for reducing power consumption of an electronic product, which comprises a processor, a power supply connection end, at least one function circuit, an input circuit, a sleep / wakeup circuit and a storage medium, wherein the power supply connection end is used for connecting a power supply for providing power for the control circuit; the at least one function circuit comprises a function unit for realizing a specific function of the electronic product and a function switch for independently controlling on and off of the function circuit; the input circuit is used for transmitting current to the function circuit from the power supply connection end and is provided with an electronic switch, and one electrode of the electronic switch is connected with the processor; the sleep / wakeup circuit is used for sending a sleep working instruction or a wakeup working instruction; the storage medium stores multiple instructions, the instructions are executed by the processor to enable the processor to receive the sleep working instruction or the wakeup working instruction; and voltage inputted to the electronic switch is controlled. The invention also provides a control method for reducing the power consumption of the electronic product. Zero power consumption of the function circuit is realized, and after the function circuit is waked up, the working state before sleep can be lasted.

Description

technical field [0001] The invention relates to the technical field of power consumption management in a power supply process, in particular to a control method and a control circuit for reducing power consumption of electronic products.
