[0035] In the related art, typec adapter is used to charge terminal equipment with typec interface, such as tablet, notebook computer and the like. Different typec adapters have different charging protocols. If the terminal equipment does not support the corresponding charging protocol, the device will not be compatible, and the terminal equipment cannot be charged. Moreover, with the increase of the number of typec interfaces of terminal equipment, different typec adapters are inserted into the typec interfaces of terminal equipment at the same time, which will cause damage to the terminal equipment due to the incompatibility between charging protocols. Therefore, how to make the terminal equipment compatible with different typec adapters has become a problem to be solved.

[0036] Based on this, the utility model provides a kind of charging control circuit, charging equipment, which can make terminal equipment compatible with different typec adapters.

[0037] Firstly, refer to Figure 1The charging control circuit is used for charging a terminal device with a typec interface, and comprises a typec interface module 100, a first control module 200, a second control module 300, a path selection module 400 and a power module 500.

The path selection module 400 is connected with the power module 500, the second control module 300 and the typec interface module 100 respectively. The typec adapter is a charger or a power adapter with a USB typec interface. When the typec adapter is connected with the typec interface module 100, the typec interface module 100 generates a charging connection confirmation signal (Connector Control, CC). The first control module 200 adopts a proportional-derivative controller (Proportional-Derivative Controller, PDC), and outputs a control signal according to the charging connection confirmation signal, to obtain a first charging control signal. The second control module 300 adopts an embedded controller (Embedded Controller, EC), and accesses the first control module 200 through a system management bus (System Management Bus, SMBus). According to the first charging control signal, the second control module 300 determines the typec interface module 100 into which the typec adapter is inserted, and records the number of typec interface modules 100 into which the typec adapter is connected. If the number is greater than or equal to 2, the priority of the typec adapter is determined according to the priority of the typec interface module 100 set in advance, and a control signal for the typec adapter is output according to the priority, to obtain a second charging control signal, which is a high-level signal.
