Overview
The ISO7710FQDRQ1 device, produced by Texas Instruments, is a high-performance, single-channel digital isolator designed to provide robust electromagnetic compatibility (EMC) and reinforced isolation. This device is particularly suited for automotive applications and is AEC-Q100 qualified, ensuring it meets stringent automotive standards. It features a double capacitive silicon dioxide (SiO2) insulation barrier, which provides high isolation ratings of up to 5000VRMS for the DW package and 3000VRMS for the D package, as per UL 1577. The device is also certified by VDE, TUV, CSA, and CQC, and complies with various safety-related certifications such as IEC 62368-1, IEC 61010-1, and IEC 60601-1.
