The invention further correspondingly discloses electronic equipment applying the multi-path power supply management method or the multi-path power supply device.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a multi-channel power supply management method and a multi-channel power supply device applied to electronic equipment. Background technique [0002] Due to different application scenarios and environmental conditions, some electronic equipment products have multiple types of power supply modes. Currently, the common electronic products in the market are two-way power supply modes, that is, two power supply types are mainly used to realize power supply. Complementary; in addition, most of the existing power switching implementations in the field are based on the two-way power supply requirements, using the ideal diode solution of the integrated circuit, or solidifying it in the power management chip with embedded software. [0003] However, when there are more power supply possibilities for electronic equipment products, for example, an electronic equipment can be connected to...

Problems solved by technology

[0003] However, when there are more power supply possibilities for electronic equipment products, for example, an electronic equipment can be connected to multiple types of power sources such as POE, USB, and adapters, the current power supply scheme for electronic products is difficult to provide flexible switching for this power supply situation And power-on guidance, on the one hand, because the existing power supply scheme is designed for the aforementioned two power supply modes, it is not suitable for other multi-channel power supply scenarios; on the other hand, usually electronic equipment does not provide two-way power supply Design special switching and power-on logic, because the two power supplies are relatively simple and they complement each other, so in many cases there is no need to consider power supply switching; on the other hand, even if there are electronic products that switch between the two power supplies , but most of them are also controlled by programs and integrated into product program algorithms that are difficult to detect
