BQ76920: How to make BQ7692003 work with BQ78350-R1A

PRABHAT RANJAN TRIPATHI

Part Number: BQ76920
Other Parts Discussed in Thread: BQ78350-R1A,

It seems that only BQ7692003 is available in the market, but the problem is it has a 3.3V LDO however, BQ78350-R1A supports only 2.5V LDO.

HOw to make the combination work?

Hello Prabhat,

You need the 2.5-V BQ76920 part if you want to power the BQ78350-R1A. You may have to use an external supply or way to step-down the voltage for the BQ78350-R1A to work and not get damaged.

I agree, but unfortunately, this information about the compatibility of BQ76920 and BQ78350-R1A is not highlighted in the datasheet.

Please mark it in future versions of the datasheet so that other designers don't face such issues?

Hello Prabhat,

I will bring this up with the team and see if we can revise it in any future revisions.

Thanks for your feedback and I apologize if it caused any issues.

Best Regards,

Heyy Luis H. S., I am in mid of my design cycle; I have all the parts and board ordered and assembled with BQ7692003. But as discussed, it will not let me use BQ78350-R1A; all my efforts will be washed away. Can you please arrange a few samples for BQ7692000PWR or BQ7692001PWR that way, I will be at least able to verify my design?

Hi Prabhat,

It looks like the ti.com store is showing they will restock BQ7692000PWR this week. I would select "notify me when available" and order samples from here.

Thanks,

Shawn
