Hey guys,

can you help me find the datasheet for the L9790 chip?

It's in the automatic transmission control unit.

Thanks.

Welcome @toommm, to the community!

unfortunately, this device has been obsolete for a long time, so no information is available from STMicroelectronics. Perhaps you know of another search engine that can find something on the otherwise never-forgetting Internet, but at least Google can't find anything useful.

Sorry not being able to provide a more pleasant answer.

Regards
