Embodiments of the present invention provide a power supply method and device. A power supply device includes: a detection module, connected to the detection pin group of the camera module, used to generate an identification signal according to the detected detection signal on the detection pin group of the camera module; a power supply identification module, and The detection module is connected to identify the type of the camera module according to the identification signal, and determine the power supply information corresponding to the type of the camera module; the power-on control module is connected with the power supply identification module and the power supply module respectively connected, and used to control the power supply sequence of the at least three power supply units of the power supply module and the power supply voltage of each of the power supply units according to the power supply information, so that the at least three power supply units provide the power supply for the camera module Group power supply. The power supply method and device adopted in the embodiments of the present invention are used to adaptively supply power to different types of camera modules used by user equipment.
Description
technical field [0001] Embodiments of the present invention relate to power management technologies, and in particular, to a power supply method and device. Background technique [0002] With the development of the integration technology of user equipment such as mobile phones, the number of cameras configured on the user equipment has also gradually developed from one to two. [0003] The cameras configured on the user equipment all need multiple power supplies, but due to the development of camera technology, cameras with different sensors have different power-on sequence requirements for the multiple power supplies they need. Considering that the resources of the platform used by the user equipment are limited, each power supply cannot be powered independently. Therefore, for each camera with different sensors, the power circuit in the platform needs to be individually designed to match the power-on sequence of each power supply. [0004] During the development or produc...
