More Information
Summary:The invention discloses a self-adaption charging circuit and a corresponding mobile terminal. The self-adaption charging circuit comprises a current limiting module, a voltage detection module and a charging circuit. The current limiting module is used for adjusting input current from an initial input current limit value so as to obtain the adjusted input current. The voltage detection module is used for detecting charging input voltage and comparing the charging input voltage with a preset voltage maintenance value so as to generate corresponding comparison results, and the current limiting module is used for adjusting the input current according to the comparison results so as to obtain the adjusted input current. The charging circuit is used for charging a chargeable element in the mobile terminal according to the adjusted input current. The self-adaption charging circuit and the corresponding mobile terminal can be matched with charging devices of various types and are wide in applied range.
