Hello!
I am creating a 2S1P design with BQ40Z60 close to the reference EMV-Design.
However, i experience voltage drops from ~12V to 8.6V on the ACP-Pin (usingBQStudio for reading this value), when the Charger is enabled.
For calibrating the PACK voltage i disable CHARGE_EN.
See attached screenshots.
The Voltage on CHARGE (see attached schematics) is not affected.
When using BQProduction with TI HPA495 calibration board, the pack voltage calibration always fails with error code 1535: voltage correction out of range.
This topic has been discussed in other threads, but unfortunately none of the answers could solve my problem.
Could you please help me with this problem?
Thank you in advance,
M.
