Part Number: BQ40Z80
Other Parts Discussed in Thread: BQ40Z50

Hi I am curious to know:

when the new firmware for the BQ40Z80 will be released;
if there is a list of versions/dates/changelog so that we can easily understand which version is which; and
if there is a way to be notified when it is released?

Kind regards,

Hi grandaphi,

1. We currently do not have a release date set for any new versions of BQ40Z80 firmware.

2. If we do release a new version of the firmware, there will be a changelog on the BQ40Z80 product page. The firmware releases will most likely follow the convention used for BQ40Z50.

3. We do not have a way to notify you when a new version is released.

Best,

Jessica

Thanks Jessica, see below:

1.This post seems to indicate there is a pending release, according to Wyatt Keller:

https://e2e.ti.com/support/power-management/f/power-management-forum/967223/bq40z80-bq40z80-unstability-at-low-soc/3574064?tisearch=e2e-sitesearch&keymatch=bq40z80%252525252520firmware%252525252520quarter#3574064

The reason I ask is that there is a known bug for the current scaling issue, that is only documented here on the forums (6 months ago), and this is very pertinent to my application:

2. Where is the changelog for the existing firmware history for the BQ40Z80? Here is an example of confusing versions:

Hello,

As Jessica mentioned we do not have a date for when the new release will be made, it is currently being developed.

Sincerely,
