Communication Module Reference Design for Functional Isolated RS-485: CAN and I2C Data Transmission
Description
The TIDA-01281 reference design is low cost: high efficiency: isolated RS-485: I2C & CAN communication module solution intended for use in industrial systems such as Uninterruptable Power Supplies (UPS) and energy storage banks that require isolated communication and isolated power for RS-485/I2C/CAN transceivers. The design has on-board C2000-Piccolo microcontroller for handling the communications protocol for each of interfaces. The board has in-built: low component count: high efficiency: primary side controlled isolated power supply to generate secondary power for communication transceivers eliminating the need for opto-coupler feedback circuits. The TIDA-01281 design is tested for data transmission under various conditions and under EFT and ESD environment: highlighting the performance of TI devices for robust data transmission in harsh environments.
