USB Type-C is a modern USB interface standard that offers a reversible design, making it easy to plug in without worrying about the orientation. This feature eliminates the frustration of trying to insert a USB drive the wrong way, enhancing user experience significantly.
Initially, smartphones used Micro USB and Mini USB for data transfer and charging. While Micro USB improved on earlier designs by offering a smaller size and better durability, it eventually became inadequate as devices became thinner and required faster data transfer and charging speeds. The limitations of Micro USB led to the emergence of USB Type-C, which not only maintains compatibility but also unifies data and power delivery into one versatile interface.
USB Type-C brings several advantages: it supports higher transfer speeds, faster charging, lower power consumption, and a more compact form factor. It also allows for greater scalability, making it ideal for future-proofing devices. As a leader in the semiconductor industry, ON Semiconductor has been at the forefront of developing solutions for USB Type-C, helping manufacturers implement this advanced technology.
Mr. Li Wenhui, Senior Field Application Engineering Manager at ON Semiconductor Mobile Market, recently shared insights on the latest USB standards and market trends. He discussed how USB Type-C, combined with technologies like Quick Charge (QC), has become a key solution for fast charging in mobile devices.
Not all Type-C ports support true fast charging, especially those limited to USB 2.0. However, ON Semiconductor’s USB Type-C solutions include power controllers that support USB 3.1, USB-PD protocols, and dynamic voltage regulation based on device needs. Their NCP81239 USB-PD synchronous buck-boost controller supports multiple fast charging protocols, including USB-PD, QC2.0, and QC3.0. It features a four-switch single-inductor design, wide input/output voltage range, and I2C bus control for precise voltage settings.
ON Semiconductor's solutions are ideal for high-reliability applications requiring adjustable voltage output and wide input ranges. They offer a compact footprint, low power consumption, and flexible design options, making them suitable for a variety of devices.
In terms of data transmission, USB Type-C can achieve up to 10Gbps speeds, supported by ON Semiconductor’s FUSB340 ultra-high-speed switch. This device supports both USB 3.1 Gen 1 (5Gbps) and Gen 2 (10Gbps), offering improved eye height and reduced jitter compared to competing solutions. It also includes features like 2KV ESD protection, low power consumption, and a small form factor, making it ideal for use in phones, tablets, and laptops.
Additionally, ON Semiconductor is working on new connector protection technology for USB Type-C, using ESD8704 devices to safeguard high-speed lines. With continuous innovation, ON Semiconductor remains a key player in advancing USB Type-C technology and shaping the future of mobile connectivity.
