Hi !

 

I have some question about ADR3533.

Our customer is planing to use ADR3533 for BMS(Automotive).

They have some issue about ADR3533.

* Immunity test condition

  =>Frequency                        ; 400-1000MHz

      Antenna position               ; In front of DUT

      Antenna direction              ; In front of H

      DUT direction                    ; Z

      Fail frequency                   ; 450~500MHz & 750~800MHz

      Phenomenon                     ; Usually the output is 3.3V.

                                                   But at the Fail frequency , the output voltage drops.

                                                   At the worst case , the output drops 2.6V. 

 

And they said that when they chose ADR3533 to other competitor device , it won't happen.

 

Q1)

Have you ever heard kind of this issue?

Q2)

If you have heard about this , can you tell us how you solve that?

Or can you give us any advice about this?

Q3)

Do you have test results for ADR3533 under the condition below?

 (Immunity test)

   *IEC62132-2 TEM CELL

   *IEC62132-4 DPI

Q4)

If you don't have some results , can you measure the test?

Q5)

If you can , can you tell us how long would it take?

 

Best regards.
