company blog about Mingjiada Electronics Supply Full Range of USB Chips – Comprehensive Coverage of Bridge, Hub, Power Management and Controller Applications

Against the backdrop of continuous iteration and upgrading of USB interface technology, Shenzhen Mingjiada Electronics Co., Ltd. continues to expand its presence in the USB chip sector. As a seasoned supplier with nearly thirty years’ experience in the electronic components distribution sector, Mingjiada Electronics has established a diverse product portfolio covering USB bridge chips, hub controllers, Type-C and PD controllers, power management chips and USB Ethernet controllers, providing one-stop chip supply services to customers in sectors such as consumer electronics, industrial control, automotive electronics, medical equipment and the Internet of Things (IoT).

I. USB Bridge Chip Series

USB bridge chips are one of Mingjiada Electronics’ core products, primarily targeting application scenarios that require the conversion of traditional interfaces (such as UART, FIFO, SPI and I²C) to USB interfaces.

Full range of FTDI USB bridge chips: Mingjiada maintains a long-term stock of genuine FTDI products, covering the three major technology nodes: SuperSpeed USB 3.0, High-Speed USB 2.0 and Full-Speed USB. Among these, the FT60x series (such as the FT600Q-B-T and FT602Q) offers a data transfer bandwidth of up to 5 Gbps, making it suitable for data-intensive applications such as high-resolution cameras and monitor connections; the H series (FT232H, FT2232H, FT4232H) offers single-, dual- and quad-channel USB bridging solutions, supporting various interface protocols such as UART, FIFO and MPSSE; the FT4232HA also provides an automotive-grade version with an extended operating temperature range from –40°C to +105°C; the X series (FT230X, FT231X, FT200XD) integrates an internal clock and MTP memory, eliminating the need for external crystal oscillators and EEPROMs, thereby significantly reducing BOM costs. The classic FT232 series, renowned for its high integration, stability, reliability and driver-free, user-friendly operation, is widely used in industrial control, communications equipment and medical instrumentation, amongst other fields.

Cypress/Infineon USB controllers: Mingjiada supplies the CY7C68013A-56LTXC high-performance USB 2.0 peripheral controller, part of the EZ-USB FX2LP series. It integrates an enhanced 8051 microcontroller core and supports both full-speed and high-speed transfer modes, with a maximum data rate of 480 Mb/s. This chip is widely used in high-speed data acquisition cards, machine vision and video processing, professional audio equipment, and embedded system development.

II. USB Hub Controller Series

With the growing demand for connecting multiple devices, USB hub controllers have become key components for expanding the number of ports.

Realtek USB Hub Controllers: Mingjiada stocks the RTS5411T-GR SuperSpeed USB hub controller, which supports USB 3.2 Gen1x1 (5 Gbps), features one upstream port and four downstream ports, and is fully backwards compatible with USB 2.0 and USB 1.1. The chip highly integrates a USB 3.2 transceiver, MCU, serial interface engine, voltage regulator and charging circuit onto a single chip, significantly reducing BOM costs. Furthermore, the Realtek RTS5490, as the world’s first USB4 hub chip to integrate Type-C/PD 3.2, supports 40 Gbps data transfer and 240 W fast charging.

Genesys USB Hub Controller: Mingjiada supplies genuine GL3590 chips from stock. This chip is a high-performance USB 3.1 Gen 2 hub controller that supports dual-channel 10 Gbps data transfer, with native support for Type-C and USB PD 3.0, utilising a Multi-Transaction Transformer (Multi-TT) architecture. It is suitable for docking stations, gaming monitors, high-end laptops and in-car entertainment systems.

Microchip USB Hub Controllers: These include the USB4604-1080HN (4-port USB 2.0 High-Speed Hub Controller), the USB2514B-I/M2 (Low-Power USB 2.0 High-Speed Hub Controller) and the USB7206C-I/KDX (6-port USB 3.2 Gen 2 Hub Controller).

III. USB Type-C and Power Delivery (PD) Controller Series

Mingjiada offers a full range of genuine TI USB Type-C and USB PD controller chips.

Product types include: USB Type-C controllers (compatible with all USB-IF specifications, delivering up to 15W of power), USB Type-C PD controllers (with integrated power paths, supporting up to 100W of power and Alternate Modes such as DisplayPort and Thunderbolt), USB Type-C adapter drivers and multiplexers (supporting data transfer rates of up to 10Gbps), and USB Type-C power path devices.

In addition, Mingjiada supplies the Cypress EZ-PD™ CCG5 series CYPD5125-40LQXIT, which features a built-in 32-bit ARM Cortex-M0 processor and 128KB of flash memory, and supports Dual Role Port (DRP), UFP and DFP modes; as well as the Hynetek HUSB252 (a USB Type-C PD DRP controller with an MCU, supporting bidirectional power delivery of up to 100W).

IV. USB Power Management IC Series

Mingjiada specialises in supplying TI USB power switches and charging port controllers. The product range covers USB Type-A and USB Type-C standards and supports the BC 1.2 charging protocol. For automotive electronics applications, TI has launched several AEC-Q100-certified products, such as the TPS25850-Q1 dual 3A USB Type-C charging port controller, which operates within a voltage range of 5.5V to 26V. In the field of high-power charging, the 30W dual USB Type-C charger reference design utilises the TPS25858-Q1 device to achieve a high conversion efficiency of 92.83 per cent.

V. USB-to-Ethernet Controller Series

Mingjiada supplies the Realtek RTL8153B-VB-CG (a USB 3.0-to-Gigabit Ethernet chip integrating a USB 3.0 bus controller and a three-speed MAC), as well as the Microchip LAN7800-I/Y9X (a SuperSpeed USB 3.1 Gen 1-to-Gigabit Ethernet bridge).
