Exclusive Headline | Hynetek, as the sole representative from the mainland chip industry, travels to Taipei for the USB-IF Compliance Workshop

USB-IF, as a renowned standardization organization for the Universal Serial Bus (USB) specification, organizes 4 to 5 Plugfest events worldwide each year to enhance technical exchanges among industry professionals and refine the certification process and types of USB-related products. Among these, one event is held outside the United States annually. This November 6th, Hynetek was the sole representative from the mainland's semiconductor industry to attend the USB-IF Compliance Workshop #132 in Taipei, China.

The main focus of testing at this 132nd  event revolves around PD 3.1 related products and chips, which will serve as a crucial opportunity for the official advancement of the PD 3.1 product ecosystem. The conference brings together representatives from manufacturers and organizations globally, allowing participating companies to showcase their USB products and latest technologies and innovations. During this event, Hynetek showcased several high-performance products including HUSB362 and HUSB380, all of which have successfully passed various functional tests (their certifications can be verified through www.usb.org).

HUSB362--USB PD Source chips supporting multi-port 140W PD3.1 power supply designs

（HUSB362  demonstration board）

HUSB362 is an MCU-integrated USB PD Source protocol chip supporting PD3.1 EPR, specifically designed for high-performance power supply applications. It supports EPR mode up to 140 W (28 V 5 A), PPS ranging from 18 W to 100 W, and AVS from 100 W to 140 W. HUSB362 features a programmable DPDM PHY where D+ and D- pins can be configured to support QC2.0, QC3.0, AFC, FCP, and Divider3 modes, ensuring excellent compatibility with traditional devices. It integrates N-MOS driver control to determine whether VIN and VBUS are conductive, thereby protecting devices connected via a Type-C connector. HUSB362 is among the first multi-port power distribution PD chips certified for PD3.1 EPR, with TID number: 9692.

During this USB-IF event, HUSB362 has achieved Shared Capacity certification. As the only domestically developed multi-port dynamic power sharing (shared capacity) PD-certified chip in China, HUSB362 enables intelligent power allocation across multiple ports, maximizing power utilization, with TID number: 10177. Moreover, we assisted CE-LINK charger, equipped with HUSB362, to successfully pass the Shared Capacity certification, with TID number: 10178. This makes it the only domestically produced multi-port dynamic power sharing (shared capacity) PD-certified charger in China.
