BQ40Z50-DEVICE-FW: BQ40Z50-R3 charge issues

eajon chen

Tool/software:

Hi Ti Team，

When we use BQ40Z50-R3 FW VERSION 3.09 and continuously charge the battery to the end of charging with SOC = 99%, after the NCT flag in the charging state is set to 1, if there is a discharge action at this time, the WDT is very likely to reset, resulting in a communication drop.

Please help confirm and release the BQ40Z50-R3 FW optimized for the above issues.

Thank you very much!

Hello Eajon,

We have received your update and due to a back log of the queue we ask for some more time until we send a response.

Thank you,
Alan

Dear Alan,

We know that the FW version 3.09, Build 90 of BQ40Z50-R3 has resolved our issue. But we don't have this FW file.Could you provide us with the srec and BQZ files of this FW?

Thank you!

Dear Alan，

The above is not the FW we need. The FW version we require is BQ40Z50-R3 3.09 build 90. Currently, the latest build available on the TI official website is 73. Please release build 90 of the FW to us.

Thank you!
