  • RE: INA226: Overvoltage Protection for INA226 – Design Inquiry

    Resolved
    Hello Ahmed, For the bus voltage you can use a transient-voltage-suppression diode. Here is an example reference design that uses one of these on the VBUS pin: https://www.ti.com/tool/TIDA-00313 . Note this design is focused for negative common modes…

  • RE: INA226-Q1: In case of using with isolator

    Hello Chase, I agree with Clemens, it would be better to add the isolator on the I2C signals. Here are a couple example designs that do this: https://www.ti.com/tool/TIDA-00313 https://www.ti.com/tool/TIDA-01608 Or, you could use a device that…
