Hi,
The bq40z50 Datasheet shows that there are 100k resistors in the SMBC and SMBD line.
How is it possible that the SMBx output driver in the bq40z50 can pull the line sufficiently down with an external 10k pull-up?
Not to mention the effect on any cable capacitance between bq40z50 and charger/host.
Please explain!
Regards,
Fred
