Hynetek PD sink controller aids in compliance with IEC 62680 new regulations

On December 7, 2022, the European Union published Directive (EU) 2022/2380, which strengthens the regulations on universal chargers and is scheduled to be mandatory in all EU countries from December 28, 2024 onwards. This revision is mainly for new production of cell phones, tablets, cameras, headphones, game consoles, speakers, e-books, keyboards, mice, navigators, headphones and laptops and other 13 types of electronic products, and laptops from April 28, 2026 onwards mandatory implementation. According to the new directive, the above 13 types of equipment must be equipped with a USB Type-C charging port that complies with the “EN/IEC 62680-1-3:2021 Part 1-3” standard and use a charging cable that complies with the same standard for charging; which supports fast charging of the device should meet The devices supporting fast charging should meet the power supply requirements of “EN/IEC 62680-1-2:2021 Part 1-2” standard, i.e., they should fully support USB Power Deliver (USB PD).

This initiative means that IEC 62680-compliant charging solutions must be adopted for relevant devices within the EU. For manufacturers, providing fast charging chips that can support USB Type-C and PD protocols is the key to smoothly entering the EU and global markets with IEC 62680-compliant products, in order to take the lead in this global market race.

As a leading supplier of intelligent fast charging solutions, Hynetek has a keen understanding of market demand and international standardization trends, and has successfully developed and launched a number of device-side PD protocol chip products that fully comply with the IEC 62680 standard. These products not only strictly comply with the relevant standards, but also excel in performance, safety and design flexibility, helping customers to comfortably meet regulatory challenges and take the lead in obtaining passes for the EU and even global markets.

Highly Integrated PD Sink Protocol Chip

The USB PD Sink Controller series products launched by Hynetek have passed the PD3.0 certification of USB-IF. They have the five major advantages of small size, low power consumption, high quality, strong functions, and certification, wildly accepted by customers.

HUSB311C

The HUSB311C is a USB Type-C PD controller that complies with the latest USB Type-C and PD3.1 standards. It implements the USB Type-C port power control for VCONN, USB Type-C CC control and sensing and USB PD Message delivery. HUSB311C has programmable Rp and Rd settings for each CC line. It does the USB type-C detection including attach and orientation. HUSB311C integrates a complete BMC encoding including a receiver and transmitter. With this physical layer of the USB BMC power delivery protocol, HUSB311C is able to handle the PD protocol and support any power up to 100W and perform role swap as needed. The BMC PD block enables full support for alternative interfaces of the Type-C specification. HUSB311C uses I2C to communicate with the TCPM via employing an INT signal for requesting attention.

HUSB239

The HUSB239 is a highly integrated stand-alone USB Type-C® and Power Delivery (PD) controller. The HUSB239 integrates the CC logic, USB PD protocol and the legacy protocols. The HUSB239 is freely to be configured by user as a Sink or DRP. Additionally, the debug accessories and audio accessories are both supported to be recognized.The HUSB239 can run in two modes I2C mode and GPIO mode. In I2C mode, an I2C master can access the HUSB239 to configure settings, read back status and perform advanced functions such as PR Swap, DR Swap, VDM messages. The HUSB239 supports PPS, SPR AVS, maximum 48 V / 5 A EPR PDO and EPR AVS in I2C mode.While in GPIO mode, the configuration is achieved via the setting pins. The HUSB239 can be configured to support maximum 28 V / 3.25 A PDO via VSET and ISET pins, only two resistors are used to set the voltage and current. And when HUSB239 acts as a source, the Rp can be configured via SRC_ISET pin. The ultra-low operation current of the HUSB239 helps the system to reduce the total power dissipation and suitable for a battery application. The HUSB239 is available in QFN 3 mm x 3 mm-16L package.
