MAXIM Integrated has released a robust family of isolated RS-485 transceivers which promises to simplify designs, thanks to integrated transformer drivers and LDOs.
Created for designers of industrial automation applications, the MAX14853/MAX14855 and MAX14943/MAX14949 family of highly integrated RS-485 transceivers allow ease of design, high efficiency and robust communications.
The range of transceivers allows simplified power and data isolated designs, thanks to transformer drivers and low drop out (LDO) regulators integrated into the transceivers.
Additional benefits include power efficiency, with the MAX14943 isolated RS-485/PROFIBUS DP transceiver, as well as the MAX14949 transceiver, each providing up to 80 percent efficiency at 150mA load.
Available in full or half duplex isolated RS-485 transceivers, the family supports up to 5kVrms and allows for robust communication up to 25Mbps. The transceivers are ideal for industrial automation, programmable logic controllers (PLC), HVAC, and power meter applications.
The high ESD transceivers are coupled with Maxim’s robust digital isolation technology, providing a highly robust, isolated RS-485 solution.
The integrated LDO helps regulate the isolated power, and provide designers with a smaller system and lower system cost.
