Part Number: BQ25883 Tool/software: Hi,
I have a question about "8.3.1 Device Power-On-Reset" in the datasheet.
1. Please tell me the time from IC startup to I2C interface is ready for communication. Please tell me the Min, Typ, and Max values…
Part Number: BQ25883 Hi Expert
Would like to check below 2 questions:
As datasheet shows we could achieve 5% in fast charge, what is the test condition?
If Q4 could closed by MCU in register setting?

Part Number: BQ25883 Other Parts Discussed in Thread: BQSTUDIO , BQ25882 Tool/software: Hi,
Am I correct in my understanding that if I want to check the voltage of VBUS>10 V using the internal ADC, I will check VBUS_ADC [14: 0]?
For example, if VBUS…
Part Number: BQ25883 Tool/software: Hi,
1) What is the maximum amount of time from when a voltage is applied to the VBUS pin until the /PG is fixed (becomes Low)?
2) Is it correct to understand that the /PG becomes Low after "Input Source Type Detection…

Hello
The layout looks good.
One last thing to consider is adding a pull down on the CE pin. It has an internal pull down but grounding or external pull down is often used.
Part Number: BQ25883 Hi Sir,
My customer has a question about the VBUS status.
When the BQ25883 w/o a battery now, and plug-in a DCP adapter, they found the VBUS status shown "USB SDP", is it correct? why?
