Maxim Delivers Smallest, Highly Efficient Isolated RS-485 Module for Industry 4.0

SAN JOSE, Calif., Oct. 31, 2018 /PRNewswire/ -- Bringing intelligence to the edge of typically noisy industrial environments calls for the high efficiency and robustness delivered by the new MAXM22511 2.5kV isolated RS-485/RS-422 module transceiver with power from Maxim Integrated Products, Inc. (NASDAQ: MXIM). The MAXM22511 dramatically simplifies and shrinks the design of field bus communications systems for factory automation, motor control and other industrial internet of things (IoT) applications.

Full industrial convergence calls for intelligence at the edge of the automated factory to enable self-diagnostic and autonomous capabilities. In order to actively monitor and communicate real-time health and status information required by these environments, factory subsystems demand field bus communications systems that meet stringent size and power efficiency requirements while supporting operations in noisy industrial environments. The MAXM22511, the first in a family of isolated communications ICs, addresses these challenges while simplifying field bus communications system designs. The highly integrated module accomplishes this by eliminating the need for discrete digital isolators, transceivers, transformers and transformer drivers while also reducing bill of materials (BOM) costs.

The MAXM22511 supports 25Mbps data rates while providing 60 percent DC-DC efficiency (2x better than competitors) and +/-35kV electrostatic discharge protection (2x better than competitors). The module is available in a land grid array (LGA) package (9.35mm x 11.5mm, which is 35% smaller than competitive solutions).  

Key Advantages

• High Integration: the module integrates isolated data and isolated power in a small package. By eliminating the need for four discrete components, it reduces BOM costs and simplifies the design.
• Power Efficiency: the module's 60% DC-DC efficiency is double that of competing solutions.
• Robust Operation: 2.5kV_RMS isolation supports reliable communication across the isolation barrier to ensure safe operation of industrial equipment. The module reduces electromagnetic interference (EMI) and its +/-35kV electrostatic discharge protection (human body model, or HBM) is twice the level of the closest competitive solution.

Commentary

• "Designers of field bus communications systems face tough challenges related to shrinking solution sizes and power efficiency," said Bassel Rahil, supplier development manager at Future Electronics. "The MAXM22511 provides a robust isolated communications solution to meet the demands of Industry 4.0 and demonstrates Maxim's continued commitment toward enabling industrial convergence."
• "Industry 4.0 brings tough demands on the underlying components for industrial equipment, from shrinking form factors to higher power efficiency and robust operation in harsh environments," said Jeff DeAngelis, managing director, Industrial Communications, at Maxim Integrated. "The MAXM22511 streamlines the design of a compact, robust and efficient field bus 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 to help optimize factory throughput and reduce lost productivity."

Availability and Pricing

• The MAXM22511 is available at Maxim's website for $7.00 (1000-up, FOB USA); also available with select authorized distributors
• The MAXM22511EVKIT# evaluation kit is available for $125
