DRV8210EVM: DRV8210EVM

Hey Ali,

Download the DRV82xxEVM Hardware Files and open the Schematic (MD033A(001)_Sch.PDF).

In the current sense amplifier block you would need to populate U4 (TLV9051IDRL) and R17 and R18 for current sensing.   TLV9051 data sheet, product information and support | TI.com  R17 and R18 are 0603 resistors.  

Alternately, you could just hook up a multimeter in current measurement mode inline with your VCC or VM power supplies.  

The reason it looks like many components are missing from the board is that we use 1 PCB to support multiple TI devices - this particular board supports all these devices, and different ones need different components populated or not.  The current sensing we included in case someone wants to use a TI current sense amplifier with our driver, but didn't populate it because it's an uncommon ask and our driver doesn't support integrated current sensing so didn't want to confuse people by implying it does.  

Hi Jacob Thompson
Thanks for your reply.
Which part number I should order for TLV9051. The one you mentioned isn't available.

Second, I will need to change R20 too seems like.

I want a very simple solution to verify the following mentioned in the datasheet.

Do you think it is possible with multimeter to measure that low current?
If i go with current sensing circuit that what else part i will need to program the mcu on board? 

Thanks again for your help.

Hi Ali,

I'll speak to the TLV9051 package. 

We haven't released the DRL package variant yet. I would recommend populating the space with the TLV9001T. It's in a DCK package but it should fit on the board if you solder it carefully on there. The pinouts also align with the footprint as well. 

Best Regards,

Hi Robert Clifton56

Thanks for reply.

What about sense resistance? Because currently it is 0ohm. I believe i will need to change it.

If you possibly can answer all above questions that would help me a lot.

Thanks 

Hi Ali,

I'll defer the rest of the questions to Jacob. I came in to help with the op amp question! 

Best Regards,

Robert Clifton 

Thanks Jacob Thompson

It helped me a lot. Now i got it what i have to do.

Thanks 

Hi Robert Clifton56
I checked further TLV9001T but I am concern if they really match the pads pitch and other critical parameters.

The space is very tight on EVM board and I wonder why they created footprint for the package that they never released yet.
Please confirm me if TLV9001TIDCKR is the best alternative to the footprint available on board. Although pin matched with each other.
Thanks

Okay,
I will order DCK package in that case.
This is the correct part number for it? TLV9001TIDCKR
Thanks
