Hello Ben,
Thanks for sending me the new information.
I'll reply to you there. I'm going to mark this thread as resolved for now.

Hello Rushikesh,
Thanks for being patient with this.
How different are the ADC measurements? Keep in mind that the ADC is mostly there as an indicator. We don't provide a spec for the ADC.
Let me know if you have any questions about this.
Also, your…
Hello Shony,
1. That is correct. Also, I think we will be setting the current limit higher in future versions of this part.
a) That's not quite what I meant to say. The converter needs to be able to read the current coming through the battery sense resistor…
HI Ethan,
Here’s the response:
Ethan Galloway said: The ICHG or ILIM_HIZ resistor will need a RC filter in parallel with them if the resistance is greater than 5kΩ.
I recommend putting place holders for an RC filter from BATDRV to BATSRC and…
Part Number: BQ25750 Tool/software: Hello,
I'm developing an battery charger based on the BQ25750 and having some strange behaviors with my board.
The charger is designed for an 8S li-Ion battery, with a charge current of 11A.
For the record: …
Part Number: BQ25750 Tool/software: Hello TI team.
When I connect battery to the BQ25750 board, I measured very high current inrush due to al-cap path.
So, If I not use the reverse mode case, how do you think as below path to protect inrush from battery…
Part Number: BQ25750 Tool/software: Hello,
Our customer wants to see BQ25750 efficiency data at L=6.8uH, Vin=20V, VBUS=24V condition as his design reference.
Could you please share this efficiency data if you have.
Best regards,
Hello Richard,
Thanks for being patient with this. I misread your original comment.
I need a bit more information to help us debug this.

Part Number: BQ25750 Other Parts Discussed in Thread: BQ25756 , Tool/software: Hello Team,
We are looking to charge from 1S-10S batteries (from 4.2V to 42V), and according to the BQ25756 calculator, to charge a 1S (4.2V) battery with Rtop = 249k, our digital…
Part Number: BQ25750 Other Parts Discussed in Thread: BQ25756 Tool/software: I am not sure where to connect the SYS terminal in this circuit. I think it should be directly connected to the battery,
but some guidance would be very welcome.
