Abstract
A charging mode auto-detection module for a charging circuit and associated charging mode auto-detection method. The charging mode auto-detection module compatibly includes a voltage dividing charging mode, a BC1.2 mode, a SAMSUNG 1.2V/1.2V charging mode and a QC3.0 mode and can detect which of the charging modes is an adaptable charging mode to a needing to be charged device and generate an indication signal indicative of a required charging voltage by the needing to be charged device so that the charging circuit can regulate its bus voltage to the required charging voltage based on the indication signal.
