BQ76PL536 EVM : false measurement result

Other Parts Discussed in Thread: BQ76PL536

Hello,

I'm trying to implement a bq76pl536 solution on a 15s pack. I'm quite surprise to see that the result in the last chip are wrong with the evaluation software, like you can see below.

Tensions should be around 3.3V, as measured with the voltmeter.

Any idea what's happening?

Thanks.

Hi Raphael,

We test every EVM before it leaves TI. How do you connect power supplies or cells to PL536 EVM?

You can find the guide line from the user's guide.

Check that and let me know.

thanks

Hi,

I found the solution in the datasheet on the IC on page 15. If less than 6 cells are used, with have to link the pins unused. That wasn't written in the start guide.

Thanks ;)
