Isolated auto-polarity RS-485 transceiver reference design
Texas Instruments
Description
This reference design demonstrates an isolated RS-485 bus node with automatic correction of a reversed bus signal polarity caused by cross-wire faults. The design provides transient protection protecting the signal path against ESD: EFT: and surge transients specified in the IEC 61000 family of transient immunity standards. An isolated DC-DC converter provides power supply across the isolation barrier utilizing the push-pull converter principle.
