Introducing the FSA646UCX from ON Semiconductor

The FSA646UCX is a cutting-edge product from ON Semiconductor, a leading manufacturer in the semiconductor industry. This device is a high-performance, low-power USB 2.0 high-speed (480 Mbps) switch featuring a single-pole, double-throw (SPDT) configuration. It is specifically designed to meet the rigorous demands of modern portable and consumer electronics, making it an ideal choice for designers looking for a reliable and efficient solution for USB signal switching.

The FSA646UCX boasts an impressive set of features that cater to the needs of high-speed data lines. It comes with built-in 15kΩ pull-up and 1MΩ pull-down resistors that ensure proper USB termination, which is crucial for maintaining signal integrity and reducing noise. Additionally, the device offers ESD protection up to ±8kV (Contact Discharge) and ±15kV (Air Gap Discharge) as per the IEC61000-4-2 standard, providing a robust shield against electrostatic discharges and enhancing the durability of the end product.

One of the key advantages of the FSA646UCX is its low on-capacitance (CON) of 6 pF (typical) and low on-resistance (RON) of 4Ω (typical), which ensures minimal signal distortion and loss, thus maintaining the integrity of high-speed data transmission. The device operates over a wide supply voltage range of 2.8V to 4.3V, making it versatile for various USB applications, including smartphones, tablets, and other portable devices where power efficiency is paramount.

Furthermore, the FSA646UCX is available in a compact µPak package, which is highly space-efficient and perfect for applications where board space is at a premium. It also supports the break-before-make feature, which prevents signal cross-talk during switching. The switch is controlled via a single input (SEL), which simplifies the interface and reduces the control line count, thereby saving additional space and simplifying PCB layout.

ON Semiconductor's commitment to quality is evident in the FSA646UCX, which is designed and manufactured to meet the highest standards. This product is not only a testament to ON Semiconductor's dedication to innovation but also to its focus on delivering solutions that enhance the performance and reliability of electronic devices worldwide.

Choose the FSA646UCX for your next design to ensure seamless USB connectivity, robust protection, and superior signal integrity in a compact and power-efficient package.
