Hi Expert,

ISO7841A-Q1 is under evaluating on customer side. EMI is the biggest concern for this project. Could you share the EMI test report of ISO7841A-Q1 for customer? Thanks.

Hi Songzhen,

Thanks for reaching out.

ISOW7841 and ISOW7841A-Q1 are the same device with the same design in them. ISOW7841A-Q1 goes through additional automotive testing and qualification and hence is Q1 qualified. Hence, we expect the same test results from both devices.

Please refer to Application Note SLLA368 that presents ISOW7841 emission test results under various configurations, I have also copied the link below.

Low-Emission Designs With ISOW7841 Integrated Signal and Power Isolator (Rev. C)

Meanwhile, I would also like to mention that we now have our second generation ISOW device, ISOW7741. The device ISOW7741 has significantly better performance compared to ISOW7841 in many ways and hence, we recommend customers to use. Please see below a comparison between ISOW7841 and ISOW7741. Thanks.
