BQ28Z610: Overtemperature condition does not trip the related FET in both charge & discharge.

Part Number: BQ28Z610

Sirs,

Overtemperature condition does not trip the related FET in both charge & discharge.

Both firmware versions(1.7 and 2.0) were tried  with no success.

Data flash values:

OTC threshold  55 degrees,  delay 2s, recovery threshold 50 degrees for charge

OTD threshold 60 degrees, delay 2s, recovery threshold 55 degrees for discharge.

Enabled protections D OTD and OTC are set.

Any help appreciated.

Thanks

Zafer Kaya
