Summary:

CX2701C is a multifunctional USB Type-C single port controller that integrates USB Type-C, USB Power Delivery (PD) 3.1, PPS, QC3.0+/3.0/2.0 fast charging protocol, Huawei FCP/SCP/HVSCP fast charging protocol, Samsung AFC fast charging protocol, VOOC fast charging protocol, MTK PE fast charging protocol, BC1.2 DCP, and Apple device 2.4A charging specification.

CX2701C specifically integrates LINK ™ Patented technology for internet communication. Through LINK ™ The CX2701C can be easily and flexibly applied to multiple Type-C port charging schemes with interconnectivity.

CX2701C adopts an external NMOS driver, with an output voltage range of 3.3V to 21V, and can provide a maximum output power of 100W. It can automatically adjust the output voltage and current according to the recognized fast charging protocol.

The output of CX2701C has CV/CC characteristics. When the output current is less than the set value, it outputs in CV mode and the output voltage is constant; When the output current is greater than the set value, output CC mode and output voltage decrease. Through a Sink/Source capable current source connected to the feedback pins of AC-DC or DC-DC, the dynamic voltage regulation function is achieved. Whether it is during startup or voltage regulation, it has a soft start/voltage regulation function, achieving a smooth voltage transition.

CX2701C has a wired compensation function, which increases the output voltage as the output current increases to compensate for the voltage drop caused by the internal resistance of the charging cable.

CX2701C has very high reliability. Built in multiple protection mechanisms to ensure equipment safety: input overvoltage and undervoltage protection, output overcurrent, overvoltage, undervoltage, short circuit and hiccup protection, etc. Start monitoring (before VBUS output, it will monitor whether the port voltage is in a safe state); DP/DM and CC1/CC2

The built-in Type-C protocol of CX2701C can support automatic wake-up when Type-C devices are inserted, intelligently recognize the forward and reverse insertion of plugs, and achieve connection. The integrated PD protocol of CX2701C supports Bidirectional Markup Coding (BMC), integrates the physical layer protocol and protocol engine of hardware, and does not require software to participate in encoding and decoding

Overvoltage protection.

CX2701C supports secondary burning and can be upgraded online.

CX2701C is packaged in QFN16 (4 * 4).
