Summary:

CX2902 chip is selectively compatible with the most suitable protocol to meet the needs of mobile phones.

The D ± of the USB Type-A port is connected to the chip. After the phone is inserted into the USB Type-A port, according to the protocol, the phone and chip will begin to recognize each other. Once the recognition is successful, the chip can respond to the phone's request. According to the request information of the phone, the chip controls the external DC/DC or AC/DC power system through the FB pin, and outputs appropriate voltage to power the phone.

In some applications, the external controller can turn off the fast charging output function of the chip through the FUNC pin, at which point the chip only outputs 5V voltage. The fast charging function of the chip can be turned off and on at any time without the need to restart the chip. The static current of the chip is less than 96uA, and the working current depends on the protocol, ranging from 80uA to 136uA. It is suitable for low-power applications, such as mobile power supplies.

Characteristic:

  • Compatible with common USB Type-A interface fast charging protocol and can be intelligently recognized

  • Protocol for mobile phone usage

  • Supports BC1.2 charging protocol

  • Supports Apple 2.4A charging

  • Compatible with high-voltage fast charging phones (Qualcomm QC2/3, Huawei FCP, Samsung AFC)

  • Compatible with low-voltage fast charging mobile phones (Huawei SCP)

  • Compatible with low-voltage direct charging phones

  • Support dynamic shutdown of fast charging output

  • Provide Huawei super fast charging, with a maximum current of 4A and 5A options

  • D ± withstand voltage 13v · static working current ＜ 96uA

  • FB voltage regulation accuracy 20mv/step

  • Working voltage range 2.9-5.5v

  • Packaging, SOT23-6

Application:

  • Car charging

  • Mobile power supply

  • Wall filling

  • Socket

  • Other USB Type-A power output devices
