Maxim: highly efficient isolated RS-485 module for Industry 4.0
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. The MAXM22511 dramatically simplifies and shrinks the design of field bus communications systems for factory automation, motor control and other industrial internet of things 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 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 package (9.35 x 11.5mm, which is 35% smaller than competitive solutions).
