TAS6424M-Q1: AC Diagnostics in PPC3

kenji gemma

Part Number: TAS6424M-Q1

Hello

I will ask you a question for the first time in this forum.

Please tell me the difference between the phase value of "Load at Device Output" and the phase value of "Load at Filter Output" in the AC Load Diagnostics Report.

If possible, please tell me the calculation formula.

Thank you.

Hi Gemma-san,

The AC diagnostic measures the impedance(and phase) across the OUTP and OUTN pin. LC filter, load are all included in the loop. To get the accurate impedance of the load itself, some calculations are required.

I've a self-made speared sheet for the calculation. Let's connect as friends then I would like to share it to you in private.

Thanks!

Regards,

Sam
