ISO7741: ISO7741FDW EFT test failed

Part Number: ISO7741

Dears,

Our customer uses  ISO7741FDW for EFT test, but the result is that the input FAU_A has no low level,but the output FAULT_A of  ISO7741F has about 1us  high level .Below is his test  setup and waveform. Could you please give me some advice?Thank you

Best regards

  • Kailyn,

    Where in the circuit is the EFT being introduced? Also, I'm having trouble reading the scope shots as they are in a different language. I am assuming that the purple channel is FAU_A and the blue channel is FAULT_A. Is that correct? Also, what are the volts per division for each channel?

    Respectfully,
