Abstract

The invention provides a voltage control method, a voltage control device, a computer readable storage medium and electronic equipment and relates to the technical field of circuits. The voltage control method is applied to a power supply end, a first configuration channel line and a second configuration channel line are included between the power supply end and a receiving end, the first configuration channel line and the second configuration channel line are used for achieving communication connection between the power supply end and the receiving end, and wire identification chips are configured on the first configuration channel line and the second configuration channel line; the method comprises steps of determining a target configuration channel line from a first configuration channel line and a second configuration channel line in response to a received voltage supply request of a wire identification chip; and configuring the target configuration channel line to output a high level so as to provide a voltage for the wire identification chip. According to the method, the voltage can be provided for the wire identification chip in a simple and convenient manner, and hardware cost is greatly reduced.

Description

technical field [0001] The present disclosure relates to the field of circuit technology, and in particular, to a voltage control method, a voltage control device, a computer-readable storage medium, and electronic equipment. Background technique [0002] USB PD (USB Power Delivery, power transmission protocol), is a fast charging specification that can support high-power fast charging. At present, in order to further improve the charging efficiency, the charging power of the power supply party (such as a PD adapter) is constantly increasing, and the charging current is also increasing. In order to ensure charging safety, the power supply party often needs to detect the overcurrent capability of the charging wire to determine maximum output power. Wherein, the detection of the charging wire is essentially the detection of the chip on the wire, therefore, it is necessary to provide a voltage for the chip. [0003] In the prior art, multiple dedicated power supply chips are ...
