Maxim MAXM2251 isolated RS-485 module transceiver

The MAXM22511 2.5 kV isolated RS-485/RS-422 module transceiver, from Maxim Integrated Products, offers the high efficiency and robustness necessary to support performance in typically noisy industrial environments.

The device is said to simplify and shrink the design of fieldbus communications systems for factory automation, motor control and other Industrial Internet of Things (IIoT) applications. The highly integrated module accomplishes this by eliminating the need for discrete digital isolators, transceivers, transformers and transformer drivers costs. It thus streamlines the design of a compact, robust and efficient fieldbus communications pathway that enables the collection of real-time health and status information from the edge of the digital factory and moves it to the cloud, helping to optimise factory throughput.

The product supports 25 Mbps data rates while providing 60% DC-DC efficiency and ±35 kV electrostatic discharge protection. It is available in a land grid array (LGA) package measuring 9.35 x 11.5 mm.
