Embodiment Construction

[0050] The core of the present application is to provide a dual TypeC intelligent transformer charging and discharging control circuit, device and method. In this solution, when only one TypeC source is inserted, the PD protocol control module obtains the maximum discharge capacity of the TypeC source, and controls the discharge The module discharges the power supply module of the system; when two TypeC sources are inserted at the same time, the PD protocol control module judges the discharge capacity of the two TypeC sources, configures the two TypeC sources as discharge devices and power receiving devices, and controls the first discharge by controlling the discharge capacity of the two TypeC sources. The switch states of the control unit, the second discharge control unit, the third discharge control unit, the fourth discharge control unit, the first charge control unit, the second charge control unit, the third charge control unit and the fourth charge control unit, so that ...

Abstract

The invention discloses a double-TypeC intelligent voltage transformation charging and discharging control circuit, device and method. The double-TypeC intelligent voltage transformation charging and discharging control circuit comprises a first TypeC female seat, a second TypeC female seat, a PD protocol control module, a charging module, a voltage transformation control module, a system power supply module and a discharging module. The discharge module comprises a first discharge control unit, a second discharge control unit, a third discharge control unit and a fourth discharge control unit; the charging module comprises a first charging control unit, a second charging control unit, a third charging control unit and a fourth charging control unit; according to the invention, charging and discharging in the double-TypeC system are separately controlled, so that the discharging capability of the TypeC source can be utilized to the maximum extent, the use requirements of different scenes are met, and the user experience is high.

Description

technical field [0001] The present invention relates to the technical field of dual TypeC, in particular to a dual TypeC intelligent transformer charging and discharging control circuit, device and method. Background technique [0002] USB Type-C is a USB interface shape standard. It has a smaller volume than Type-A and Type-B. It can be applied to both PC (master device) and external devices (slave devices, such as mobile phones). Interface Type. USB Type-C has 4 pairs of TX / RX split lines, 2 pairs of USBD+ / D-, a pair of SBU, 2 CCs, and 4 VBUS and 4 ground wires. [0003] The traditional dual TypeC charge and discharge display system is mostly charged and discharged in the same gear, which will cause the TypeC source and discharge capabilities to be underutilized. For example, if the discharge capacity of source C0 is 5 / 9V / 12V / 20V, and the charging capacity of source C1 is 5V, it can only be charged and discharged at the 5V gear. If charging and discharging are controlle...
