Part Number: BQ27750
Hello,
Please answer each of the following items.
①Does the bq27750 chip have a problem with I2C communication?
②Is there any information not feedback in the latest bq27750 data sheet?
③Does bq27750 support I2 communication?
④What is the IOL limit for bq27750?
「6.25 I2C Interface I/O」 on page 11 of the bq27750 data sheet states that IOL = 3mA, so I think the upper limit is 3mA or more.
⑤In the case of IOL=3mA, there is the description that the maximum VOL is 0.4V in both bq27750 and bq27545data sheets.
There is a difference when comparing each VOL with our PCB.
What differences in hardware will cause this difference?
I want to know the mechanism.
It will be helpful if you can answer as soon as possible
Sincerely,
