With the MAX22505 ±40V high-speed USB fault protector from Maxim Integrated Products, designers can now eliminate USB port damage from all faults, including ground potential differences, up to ±40V without the tradeoffs required by competing solutions. It protects data and power lines from industrial equipment powered at 24VAC and 40VDC, while also reducing solution size by more than 50% for industrial voltage applications.

Industrial environments continue striving to reduce solution footprint to increase productivity and throughput while demanding system robustness and increased uptime. As a result, there has been a trend to adopt USB vs. RS232 on automation equipment due to a much smaller connector size. As industrial environments adopt USB to provide faster communication for applications such as real-time diagnostics, programming/service ports on programmable logic controllers (PLCs), or supporting camera vision systems, USB ports require fault protection from overvoltage and ground differences while balancing the need to support high-speed data rates up to 480Mbps.
