FS112 in stock, CX2902 perfectly replaces FS11X USB Type-A fast charging protocol IC, TD, FS112, LT6602, providing CX2902 samples and technical support! CX2902 supports all protocols and supports up to 4A output capacity for SCP.

CX2902 is used for intelligent management of the fast charging protocol of the USB Type-A port. The so-called "intelligence" emphasizes that it can automatically recognize different phone models and choose the best fast charging method to charge them.

The phone brands supported by CX2902 include but are not limited to: Huawei, Apple, Xiaomi, OPPO, VIVO, Samsung, Nubia This means that after using the CX2902 charger solution, users can quickly charge various mainstream mobile phones. Typically, there are 2-3 or more brands of mobile phones in a household. With the built-in CX2902 charger, consumers no longer need to search for "original" chargers to adapt to specific phone models.

CX2902 can be used for various types of chargers such as car charging, wall charging, mobile power supply, and plug-in. The chip is packaged in SOT23-6L, greatly saving PCB board space, making it convenient for the charger solution to achieve miniaturization and portability. In terms of functionality, compared to the current solution, the CX2902 has added support for Huawei phones that use SCP fast charging and OPPO phones that use VOOC fast charging.

CX2902 chip provides a cost-effective and highly integrated solution for USB Type-A fast charging intelligent management.

CX2902 can work with various types of DC/DC or AC/DC power chips. If the power chip has a 4A output capacity, you can choose the CX2902. After increasing the charging power, it will bring additional requirements such as heat dissipation and wire withstand voltage. Therefore, equipment manufacturers need to consider high-power charger design and provide customers with suitable charging wires to ensure charging safety.

CX2902 chip is a selective and mainstream charging protocol, which can intelligently identify the type of phone inserted and choose the most suitable protocol to meet the needs of the phone. 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 agreement, the phone and chip will start to recognize each other. Once recognition is successful, the chip can respond to the phone's request, and based on the phone's request information, The chip controls the external DC/DC or AC/DC power system through FB pins, outputting appropriate voltage to power the mobile 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。

Range: 80uA~136uA,Suitable for low-power applications, such as mobile power supplies.
