CCS/BQ76PL455A: Request of data

Part Number: BQ76PL455A

Tool/software: Code Composer Studio

Hi,

I'm using a BQ76PL455 for balancing of 14 cells. I'm not using a TMS570S, but a Mircochip. How can I request an output signal from the AUX channels. I read the software design reference, but there was no advice for reading out the voltage on the AUX-Channels.

Which device and Register do i have to request as a hex code?

How can I further transfer the response code into the actual voltage?

Kind regards,

Hi Roman,

There is no specific register to read back the hex data, it will be returned when you send a command in the command register to read the AUX data. Please read over section 7.3.3.1 of the datasheet closely.

You can then convert the hex data into actual voltage by using the conversion in datasheet section 7.3.3.5 after converting to decimal.

Regards,

Taylor

Thanks, but how can I then get the values of all AUX-Channels?

Maybe I have missed it in all the sheets.
