Part Number: TIDA-01606
Other Parts Discussed in Thread: AMC3330

Team,
-Can you please confirm that the Hardware changes listed at page 41 need to be implemented on the TIDA-01606 - REV-6 board?
https://www.ti.com/lit/pdf/tidue53
What those changes are related to?

-The AC Voltage measurements Vinv and VG are not isolated from the schematic (screenshot below from Power Board Schematic Sheet 4).
Is there any specific reason to it?

Thanks in advance,

A.

    Hi,

    yes I can confirm you that if you would like to run TIDA 01606 with both control card 0039C you need to apply the hardware modifications listed there.

    Related to the voltage isolation, in this reference design we have implemented a resistive divider approach for measuring the voltages. If you would like to have isolation you can use AMC3330 solution.

    Thanks

    Best REgards
