June 4, 2018—With the MAX22505 ±40V USB fault protector from Maxim Integrated Products, Inc. (NASDAQ: MXIM), designers can eliminate USB port damage from all faults, including ground potential differences, up to ±40V . It protects data and power lines from industrial equipment powered at 24VAC and 40VDC.
The MAX22505 is a solution that combines USB fault protection (480Mbps) for industrial voltages, while being flexible to support either host or device applications including USB On-The-Go (OTG). It protects equipment from overvoltage or negative voltage on power and data lines, as well as ground potential differences between devices. Housed in a 24-pin 4mm x 4mm TQFN package, it operates over the -40°C to +105°C temperature range. Applications include building automation, industrial PCs, PLCs, and diagnostic USB ports.
