Designers of industrial automation equipment require solutions that provide flexibility and high efficiency. The high integration of the RS-485 family of transceivers with integrated transformer drivers and low drop out (LDO) regulator simplifies power and data isolated designs. The MAX14943 isolated RS-485/PROFIBUS DP transceiver, as well as the MAX14949 transceiver, each provide up to 80% 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.
Key Advantages
- Ease of design: Simplifies design and provides flexibility through integration; transceivers include a transformer driver and an LDO
- Robust communication: 2.75kVrms and 5kVrms isolation options protect against large differences in ground potential between ports; Robust ±35kV (HBM ESD) on driver outputs/receiver inputs
- High efficiency: Integrated transformer driver provides up to 80% efficiency at 150mA
load - Available in a 16 pin W-SOIC package (11mm x 11mm).
- Specified over the -40-degree Celsius to +105-degree Celsius temperature range.
