Other Parts Discussed in Thread: BQ40Z50

good day, Colleagues,

My customer tries to implement the BQ40Z50 for 1S configuration, but the register "FET_EN" doesn't answer. Customer can't get an access. Please, see attached picture from the BQ Studio.

Could you tell me, what customer should check?

Thank you, Mike

The "FET_EN" does not return any value. It will only toggle between FW FET control or Manual FET control. If you refresh the "Registers" screen after issuing this command, you should see the "FET_EN" change from green -> red or red -> green.
