Isolated RS-485 reference design with integrated signal and power

TIDA-00892

Overview

The TIDA-00892 reference design provides a compact solution capable of generating isolated DC power while supporting isolated RS-485 communications. This reference design contains a reinforced digital isolator with integrated power supply and an RS-485 communications transceiver.

characteristic

● Small combo solution (equivalent to ISOW7841 device size)
● Single power supply solution (no separate power supply is required on the interface side)
● BOM cost reduction
● Expandable to other full-duplex RS-485 transceivers
