THS4503EVM: About THS4503EVM Schematic

Hi Taroimo,

Was the error you are referencing based off a difference you saw in a physical board and was measured? Or is it a question when just looking at the schematic?

Hi Ignacio,

On the actual EVM, I have confirmed that the pad on one side of R14 is connected to VS- instead of GND.

Therefore, I also compared the schematic in the EVM user guide and the layout, but I think there is a discrepancy between the two.

Please tell me which is "true", the schematic or the layout.

Best Regards,

Taroimo

Hi Taroimo,

I had trouble locating a spare EVM to confirm your findings, so I ordered an EVM which will take a few days to arrive to confirm the layout. I will get back to you as soon as I have an answer. Thank you for your patience.

Best Regards,

Hi Ignacio,

Thank you for your confirmation.

I've checked the layout of both sides of the EVM by overlaying them, so I'll send it to you.

Hi Taroimo,

Thank you for the image and I do see your concern; I will get back to you as soon as I have a definitive answer which should be by next week.

Hi Ignacio,

Thank you for your confirmation.

From now on we will consider the EVM layout to be correct, not the schematic.

Best Regards,

Taroimo
