Abstract

The invention provides a double-charger charging circuit. The charging circuit comprises a first OVP chip and a second OVP chip. The first OVP chip comprises a first voltage input pin and a first voltage output pin. The second OVP chip comprises a second voltage input pin and a second voltage output pin. The first voltage input pin is used for being connected with a first charger, and the first voltage output pin is used for being connected with to-be-charged equipment. The second voltage input pin is used for being connected with a second charger, and the second voltage output pin is used forbeing connected with the to-be-charged equipment. According to the double-charger charging circuit provided by the invention, when the two chargers charge the to-be-charged equipment at the same time, the charger with relatively high power is preferentially used to charge the to-be-charged equipment, so that the charging efficiency is improved. If the voltages of the two chargers are equal, the to-be-charged equipment is charged by the two chargers at the same time, so that the power of an input power supply is further improved. A quick charging function can be realized, and the cost of the charging circuit is relatively low.
