Part Number: BQ25750 Tool/software: Hi TI team,
We are currently developing with the BQ25750 and have observed ringing on the switching node.
Here are our test conditions:
Switching frequency : 350 kHz
Buck mode : VIN = 13.6V, VBAT = 10.95V
Boost…
Hello Ethan,
We did the redesign and now it works very well without any problems. This time we used the BQ25756 as it is more suitable for our application.
We paid special attention to filtering and capacitors in general.
Thank you very much for your…
Part Number: BQ25750 Tool/software: Hi,
We use the BQ25750 for battery charge, our input voltage is 47-54V, and the output is unloaded without a battery. The STat1/STAT2 indicator lights on the chip flash alternately very quickly,
and soon the chip is…

Part Number: BQ25750 Tool/software: Dear TI support Team,
We are evaluating the BQ25750 and would like to confirm whether it supports the following function:
Can the battery supply power back to the input (VAC) under certain conditions?
If yes,…

Hello There,
Today a colleague reviewed my schematic, and he noticed that I forgot the diodes on the BTST pins.
Now I wonder if these diodes are necessary since table 6-1 in the datasheet indicates that the DRV_SUP…

As shown in the picture, please help to determine whether it is a BQ25750 series product through silk screen printing. Or what other model of product is it?…
Part Number: BQ25750 Tool/software: Hi Team,
We are planning to use BQ25750 battery charger IC in our design. Can you please share if any calculation sheet available for this battery charger IC?
Thanks
Hello Rannie,
That's a good question. The BATFETs will turn-off once the current exceeds 8A. When the BATFETs turn-off from the current limit, the BATFETs will wait around 3ms and then proceed to try to turn-on again.
Best Regards, Ethan Galloway
