Small Form Factor: Half-Duplex With Isolated & Non-Isolated RS485 Interface Reference Design
Texas Instruments
RS485 (Isolated: Non-isolated) is a popular interface for the Grid Infrastructure space: and is one of the most important options on newly designed equipment. TIDA-00308 will enable customers to quickly evaluate and design with TI RS485 devices for 3 different application scenarios: with an isolated power supply provided in this design. Additionally: test results in the user’s guide will demonstrate the IEC61000-4-2 ESD and IEC61000-4-5 surge tests performed on this design.
Features
- One design demonstrates three RS485 application scenariosTwo isolated power are provided: 5V and 3.3VRS485 transmit and receive status are indicated by LEDSame design is compatible to multiple TI isolation devices to meet different application needsDesigned for IEC-61000 complianceIEC-61000-4-2: ESD up to 4KV contactIEC-61000-4-5: Surge up to ±1KVTargeted for applications such as Interface through isolator Non-isolated RS485 transceiver Isolated RS485 transceiver
