BQ40Z80: 0_04 bug fixes for 6S implementation

Dmitriy Krlv

Part Number: BQ40Z80

Hello. I understand that the bug with the use of DISP pin (high current and heating of the microcircuit) in firmware 0_04 has not been resolved. Do you have a firmware release where it has been fixed? More than two years have passed, I am now making a new 6S board and am afraid that I will face similar problems again.

Here is a links to a description of the problem. As far as I remember, there were also problems with PDSG and a few more minor ones. Have you done any work in this direction? What pins does DISP and PDSG work on?

Hello Dmitriy,

Sorry for the delay, we do not have a fixed schedule yet to release the BQ40z80-R1. Due to the holidays it will most likely be beginning of 2022 (Q1/Q2), but this can change. I will update if the schedule becomes confirmed.

Sincerely,

Wyatt Keller
