With the popularity of the USB PD fast charging technology, cables are becoming more and more important as a medium for power transmission between devices. Especially in the working condition of high voltage and high current, not only the material and wire diameter of the wire are required, but also need to join the E-Marker chip certified by USB-IF Association (The cable with E-Marker chip can support the maximum current of 5A. , cables without E-Marker chips can only support up to 3A current).
A full-featured USB-C cable must be added to the E-Marker chip because the E-Marker chip is pre-written with various cable specifications, current carrying capacity, and data transmission capabilities. The electronic device also uses this chip to Get the cable information to determine the power supply or data transmission mode to achieve the protection effect.
Recently, the domestic chip manufacturer Shenzhen Hui Neng Tai Semiconductor Technology Co., Ltd. has launched an E-Marker chip HUSB330, and has obtained the certification of the USB-IF Association, TID No. 100,060, XID No. 0005396. This is also the first E-Marker chip in mainland China that has achieved USB-IF certification and mass production. It has achieved a domestic E-Marker chip from scratch and has significant historical significance for localization of the chip.
Charging head network uses the ChargerLAB POWER-Z FL001 super test cable equipped with Huinengtai E-Marker chip, can read this cable to support USB 3.1 Gen2 data transmission, supports maximum 20V/5A power transmission, and supports 10GHz ultra-high speed Data transmission and other parameters.
Through the dismantling of the charging head net, it was found that this USB-C cable uses Hynetek E-Marker chip HUSB330, supports USB Type-C 1.2 and PD2.0/3.0 standards, and passed the USB-IF Association certification.
Hynetek Hui Neng Thai HUSB330 uses DFN-8L 2mmx3mm and DFN-6L 2mmx2mm two kinds of encapsulation methods. It is powered by VCON1 or VCON2 and supports a wide voltage range of 3.0V-5.5V. The HUSB330's self-contained multiple-programmable memory unit (MTP) can support multiple reprogramming or programming locks. It can also support CC-pin implementation of a Type-C finished product or a finished cable system.
Hynetek Hui Neng Thai HUSB330 details.
USB PD fast charging is accelerating and popularization. High-power devices have increasingly higher requirements for charging cables. At present, most of the domestic E-Marker cables are also based on imported chips and have strong dependence. The introduction of the Hynetek Hui Nengtai HUSB330 broke the situation in which the E-Marker chip was controlled. We also have reason to believe that this is only the beginning of an E-Marker chip localization. We will see more domestic E-Marker chips in the future.
