The present invention provides a charger USB charging control circuit and a charger, and the circuit comprises a USB female seat, a first control chip, a first switching device, a first anti-reversing module and a second anti-reversing module. The USB female seat comprises a power supply line P+, a grounding line P-, a data line positive electrode D+, and a data line negative electrode D-. The first control chip comprises a power supply pin, a voltage output pin, a signal output pin, a signal control pin and a signal receiving pin. The power supply line P+ is connected to the power supply pin, and the grounding line P- is grounded. The data line positive electrode D+ is connected to the voltage output pin through the first anti-reversing module and is also connected with the signal output pin through the first anti-reversing module and the first switching device. The control end of the first switching device is connected with the signal control pin, and the data line negative electrode D- is connected with the signal receiving pin, and is also grounded through the second anti-reversing module. The above control circuit can effectively improve the charging efficiency. In addition, the invention also provides a terminal USB charging control circuit and portable multi-function equipment.
Description
technical field [0001] The present invention relates to the technical field of USB charging. Specifically, the present invention relates to a charger-end USB charging control circuit and a terminal USB charging control circuit, and also relates to a charger and a portable multifunctional device. Background technique [0002] USB is the abbreviation of Universal Serial Bus (Universal Serial Bus), which is an external bus standard used to regulate the connection and communication between computers and external devices. The USB interface supports the plug-and-play and hot-swap functions of the device, and the charging and data transmission can be performed through the USB interface. In recent years, the USB interface has become a standard data interface and charging interface for various portable smart terminals. However, when the smart terminal is charged by the USB charger, the charging current is relatively low, resulting in poor charging efficiency. Contents of the inven...
