With broad compatibility across USB 2.0, USB 3.2, and 40Gbps high-speed cables, it offers a cost-effective solution for the growing USB-C ecosystem. According to ChargerLAB, the HUSB332 has been adopted by leading brands such as Lenovo, Samsung, and Honor.
Hynetek HUSB332
The Hynetek HUSB332 is a high-voltage E-Marker chip developed by Hynetek Semiconductor Co., Ltd. It has received USB-IF certification (TID: 875) and incorporates a series of performance enhancements and reliability improvements based on extensive market feedback. Notably, the CC, VCONN1, and VCONN2 pins support up to 25V overvoltage protection. Additionally, it supports Thunderbolt 3 40Gbps high-speed data communication, the Modal Operation command, and the Get Manufacturer Info command. The chip also features options for multiple reprogramming and one-time programmable (OTP) lock functions.

Designed to accommodate various USB application environments, the HUSB332 can be integrated into USB 2.0 (5A), USB 3.0, USB 3.1, USB 3.2, and 40Gbps high-speed cables. By eliminating decoupling capacitors on the VCONN1 and VCONN2 pins, it enables a zero-external-component design, simplifying system implementation and reducing overall costs.

The HUSB332 is an ideal solution for USB Type-C cables requiring electronic markers (eMarker) and power delivery. It ensures safe and efficient power negotiation in high-power charging applications and supports high-speed data transfer in Thunderbolt 3 environments.

ChargerLAB POWER-Z KM003C shows it supports USB2.0, has a power transmission capacity of 20V5A, and supports 100W PD fast charging.
