Abstract

The technical scheme of the invention comprises a mobile power supply control device based on a Type C protocol and a PD protocol. The mobile power supply control device comprises a Type A port detection device, a charging device, a boost device, a power control device, a DPDM protocol device, a scene control device, a Type C protocol device and a PD protocol device. The mobile power supply control device has the beneficial effects that the resource is reduced, and the cost is reduced; and switching among charging and discharging at 5V, simultaneous multi-port discharging at 5V, single-port high-voltage charging, single-port high-voltage discharging and various scenes is supported by a single chip, the problem of charging and discharging of a mobile power supply at low power is effectivelysolved, and the risk of reverse charging of a mobile phone on the mobile power supply is effectively reduced.

Description

technical field [0001] The invention relates to a mobile power supply control device based on the TypeC protocol and the PD protocol, belonging to the field of computers. Background technique [0002] Most of the existing mobile power supply USB PD solutions adopt the mode of MCU+PD protocol chip+Power chip, using multiple chips, a large amount of memory cache is required inside the circuit to store sending and receiving messages, which requires more resources and complicated control , expensive. For charging while discharging and multi-port simultaneous discharging, the existing mobile power USB PD solutions generally do not support or use multiple chips. For charging management when the power bank is low, the TypeC protocol does not give good suggestions. When the mobile power supply charges the mobile phone, the TypeC protocol has the risk of the mobile phone charging the mobile power supply in reverse. Contents of the invention [0003] Aiming at the deficiencies of...
