Unfortunately the tool is no longer available since the device is NRND. Why are you trying to use this device. Why not the bq27320 or the bq27220?

thanks

This is PCB Board is old model which has this BQ27200 and they were tested manually, I need to to auto testing.

That's the reason I'm asking. I need to find a way to make it work.

Hi Onyx,

I am working with Nhizanth on this:

We been able to communicate with the BQ27200 using Labview and EV2400. There's one issue we have is the conversion formula for Temperature measurements.

SLUS556D calls for this formula:

Temperature = 0.25 * (256 * TEMPH + TEMPL)

Temperature Registers (TEMPL/TEMPH) — Address 0x06/0x07

Here's what we read:

Read from 0x06: 0xA8

Read from 0x07: 0x04

We tried the formula from SLUS556D, it doesn't represent the expected temp.

Need your help on what should be the correct formula for Temp Measurement for BQ27200.

Hi Sime,
Did you figure this out yet?

For this case above, what is the actual temperature being measured.

Thanks

Would you be willing to share some basic information regarding how you are "able to communicate with ... using Labview and EV2400"?

Hi Corey,

Unfortunately we do not have sample code in labview to communicate with the device.

thanks
