Overview
The ISO1050DWR is a galvanically isolated CAN (Controller Area Network) transceiver produced by Texas Instruments. It is designed to meet the specifications of the ISO11898-2 standard, ensuring reliable and isolated communication in various industrial and automotive applications. The device features a silicon oxide (SiO2) insulation barrier, providing high levels of galvanic isolation up to 5000 VRMS for the DW package and 2500 VRMS for the DUB package. This isolation prevents noise currents and interference from affecting sensitive circuitry, making it suitable for harsh environments.
