Hello, the FUSE pin of BQ40Z80 is floating. The fuse enablement is all closed. Why is the charging and discharging MOS still turned off and FUSE alarms.May I ask what causes.

Hello Jingming,

Can you log your test using bqStudio? Also share your .gg file so we can look at all the settings.

All the factors that will disable either FET is described in the TRM, section 5.12 Charge Disable and Discharge Disable. Are you sure it's linked to the FUSE specifically?

Sincerely,

Wyatt Keller
