Overview
The ISO6762FQDWRQ1 is a high-performance, six-channel digital isolator produced by Texas Instruments. This device is part of the ISO676x-Q1 family, which is designed for cost-sensitive applications requiring robust isolation and high electromagnetic immunity. The ISO6762FQDWRQ1 is AEC-Q100 qualified, ensuring it meets stringent automotive standards with an ambient operating temperature range of –40°C to +125°C. It features a 50 Mbps data rate and is certified by various regulatory bodies including VDE, TUV, CSA, and CQC.
This isolator is ideal for use in conjunction with isolated power supplies to prevent noise currents on data buses, such as CAN and LIN, from damaging sensitive circuitry. The device is available in a 16-pin SOIC wide-body (DW) package and is a pin-to-pin upgrade to older generations, enhancing system-level ESD, EFT, surge, and emissions compliance.
