With Maxim’s MAX14853/MAX14855 and MAX14943/MAX14949 highly integrated RS-485 transceivers, engineers can easily design efficient industrial automation equipment, programmable logic controllers, HVAC, and power meter applications. The integration of the transceivers with transformer drivers and an LDO regulator simplifies power- and data-isolated designs. The MAX14943 isolated RS-485/PROFIBUS DP transceiver and the MAX14949 transceiver offer up to 80% efficiency at 150 mA load. Available in full- or half-duplex isolated RS-485 transceivers, the family supports up to 5 kVRMS and allows for robust communication up to 25 Mbps.
The transceivers are available in a 16-pin W-SOIC package (11 mm × 11 mm). They are specified over the –40°C to 105°C temperature range. Evaluation kits are currently available:
