Product Overview: MAX4987AEETA+T from Maxim Integrated
The MAX4987AEETA+T is an advanced USB 2.0 high-speed analog switch with overcurrent protection, designed and manufactured by Maxim Integrated. This compact and efficient integrated circuit (IC) is specifically engineered to provide a robust interface solution for USB applications where fault protection and high-performance switching are critical.
Encased in a tiny 16-pin TQFN package, the MAX4987AEETA+T offers a minimal footprint on the PCB, making it an ideal choice for space-constrained applications. The device is capable of switching two USB downstream ports between two USB upstream ports, allowing for versatile connectivity in USB hubs, docking stations, and other multifunction peripherals.
One of the standout features of the MAX4987AEETA+T is its built-in overcurrent protection. This safety mechanism is designed to shield the USB ports from excessive current that can arise from accidental short circuits or faulty connected devices. The IC automatically disconnects the faulty port in the event of an overcurrent condition, thereby protecting both the switch and the upstream host from potential damage.
The switch's high bandwidth (1GHz) ensures that it does not become a bottleneck for high-speed USB 2.0 data transfer, which can reach up to 480Mbps. Additionally, the MAX4987AEETA+T boasts low on-resistance (RON) of just 4.5Ω (typical), which minimizes voltage drop and power loss across the switch, thus ensuring reliable and efficient operation.
For ease of implementation, the MAX4987AEETA+T supports both 1.8V and 3.3V logic levels, providing flexibility in various system designs. The device also features thermal-shutdown protection and under-voltage lockout (UVLO), further enhancing its protective capabilities and ensuring stable performance under varying conditions.
As a product of Maxim Integrated, a company known for its high-quality and innovative integrated solutions, the MAX4987AEETA+T represents a reliable and high-performing choice for designers looking to incorporate USB switching and protection functionality into their applications.
