Could the MC33771C Evaluation Board can work in Stand Alone mode?

[thesunminh2]

Hello, I have a question about the MC33771C Evaluation Board. I intend to test the OC & OV protection function of the MC33771C by using the Evaluation board FRDM33771CSPEVB.

Could I operate the EVB of MC33771C stand alone, without using the EVB S32K? I intend to control the MC33771C by using the SPI emulator, is it possible to do this? And if it is possible, which information/register that I should modify/input to the MC33771C before connecting to the battery cell and starting test?

Best regard.

Dear guoweisun,

Thank you for your support.

If I want to check the OC, OV operation of MC33771C, which control board that I should use ? 

And could you tell me how to check the OC, OV operation generally?

Best regard.

I think each EVB has this OC/OV detection function.

For example you can set CTx_OVUV_EN bit then read CELL_OV_FLT bit for OV.

Dear guoweisun,

Thank you for your reply.

Do you mean that I can check that as if the MC33771C can detect the OC / OV normally or not by using the MC33771C evaluation board only, no need to use the control board, right?

The produce is like as below generally, right?

1. Change the register setting of OC/OV threshold

2. Input the OC/OV signal

3. Read the status register to confirm.

If an POR /wakeup event is needed to make the IC operate, please kindly tell me know.

Best regard.

That's better for use the controller board to change the software to detected the OC/OV

We provide the software driver example as below:

Thank you, I got it.

That's difficult to operate this IC stand alone.

The better way to test it by software code.
