Abstract

The present invention belongs to the charging control field and provides a charging control circuit and a charging device. According to the embodiments of the present invention, a first voltage control module carries out voltage reduction or voltage maintaining processing on direct current and then outputs preset low-voltage charging current; a second voltage control module carries out voltage boosting processing on the direct current and then outputs preset high-voltage charging current; and therefore, the charging control circuit can output two paths of charging voltage, and different charging needs of users can be satisfied.

Description

technical field [0001] The invention belongs to the field of charge control, in particular to a charge control circuit and device. Background technique [0002] The emergence of electronic equipment has brought great convenience to human production, life and study. Many electronic equipment have built-in batteries, which are convenient for carrying electronic equipment. [0003] At present, the battery power of electronic equipment is limited, and it needs to be charged when the power is low. However, the current charging circuit generally only has a single charging circuit, a fixed charging mode of voltage and current, and cannot use low-voltage or high-voltage charging methods according to needs. . Contents of the invention [0004] The object of the present invention is to provide a charging control circuit, aiming at solving the problem that the charging current of the existing charging device is fixed and cannot be charged with low voltage or high voltage according t...
