Key Document
Description
The TIDA-00892 reference design provides a compact solution capable of generating isolated DC power while supporting isolated RS-485 communication. The design consists of a reinforced digital isolator with integrated power combined with an RS-485 communication transceiver.
Features
- Small Combination Solution (Equal to ISOW7841 Device Footprint)
- Single Power Supply Solution (No separate supply required for interface side)
- Reduced BOM Cost
- Extendable to Other Full-Duplex RS-485 Tranceivers
