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 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…
Hello Ben,
Ben said: It is difficult working FET swap test due to drain pad and via
Swapping the FETs is always really difficult. Any FET with a lower VTH should do. A FET like the SiR680LDP, SiR880BDP, or AONS66920 should work.
Here's the procedure I…
Hello Ben,
Thanks for being patient with this.
From our testing, a lower resistance is better and a capacitance of 8nF to 20nF works well for the circuit.
Also, it looks like the power path function of your circuit is working well. Let me know if you…

Hello,
I'm using the BQ25750 for a new design which have an integrated 50V 15A battery charger, but I have some difficulties to make it work correctly.
Do debug it, I made…
Hello Toshiro,
Toshiro Imi said: I understood that none of our 10 cell battery chargers do not support supplement mode. Could you tell me why these chargses do not have suppliment mode ?
This is related to the design of the charger. We can't include every…
Part Number: BQ25750 Tool/software: By default, the BQ25750 has an automatic power path switchover. When the VAC power is out the of range set by the ACUV/ACOV resistors, system power will change to VBAT. When VAC is in range again, system power will…
Part Number: BQ25750 Tool/software: Hi all,
I am posting this question again because unfortunately I can't find my previous post.
I designed my battery charging board based on TI BQ25750. Looks that almost everything works OK, except the STA1 STAT2…
Hi Ethan,
I think VAC_DPM is the most likely candidate for the behaviors I'm seeing. I believe I wrongly assumed VAC_DPM was selectable or related only to MPPT mode or something. Long story short, it was ultimately a misunderstanding of the function…

I´m designing an PCB with the BQ25780 and have some strange behaviour with the current measurement.
In my first design I realized, that the measurement…
