  • RE: INA240: High common mode voltage. 230V

    Resolved
    Hi Luuk, The INA138 floating circuit will not work well as an inline current sensor, because it is unidirectional. There are circuit examples in the datasheet for bidirectional current sensing. You might be able to adapt them similarly into floating ones…

  • RE: UCC28711: TIDU412A Power Supply Design Issue

    Hi Ahsan, Apologies for the delayed response. With this indirect input voltage sensing method, any leakage in the transformer will impact the resulting voltage at J5. It is not a precise method for sensing the input voltage. If a more precise is needed…
