Abstract

The invention relates to a charging control circuit of an intelligent charger. The charging control circuit comprises a load detection circuit, a voltage input circuit, a control circuit and a charging circuit, wherein the load detection circuit is used for detecting and recognizing a charging protocol type of a load accessed to the intelligent charger, and generating a feedback signal according to the recognized charging protocol type; the voltage input circuit is used for a user to input an adjustment voltage value; the control circuit is used for receiving the feedback signal and the adjustment voltage value and generating a voltage control signal according to the feedback signal or the adjustment voltage value; and the charging circuit is used for adjusting an input voltage according to the voltage control signal and then forming an output voltage to charge the load. By the above charging control circuit of the intelligent charger, except the power supply demand for a normally-used device is met, the electricity utilization demand of a particular load also can be met, and the charging control circuit is high in compatibility. The invention also relates to the intelligent charger.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to an intelligent charger, and also relates to a charging control circuit of the intelligent charger. Background technique [0002] Traditional chargers can only output a single voltage, and different electronic devices may have different voltage requirements, so each needs to be equipped with a charger for charging, and the compatibility of the charger is poor. Contents of the invention [0003] Based on this, it is necessary to provide a charging control circuit of an intelligent charger with better compatibility. [0004] A charging control circuit of an intelligent charger, comprising a load detection circuit, a voltage input circuit, a control circuit and a charging circuit; the load detection circuit is used to detect and identify the charging protocol type of the load connected to the intelligent charger, and according to The identified charging protocol type genera...
