Part Number: BQ7718 Other Parts Discussed in Thread: BQ2947 , I hope use BQ7718xy OVP level 3.85V or 3.90V.
It is commented contact to TI on datasheet.
I also want to know about BQ2947. It is similar to BQ7718. I want to 3.85 or 3.9V OVP Level too.
Please…
Part Number: BQ29400 Other Parts Discussed in Thread: BQ2947 Hi team,
on TI.com it says, that BQ29400PW is replaced by BQ294700DSGR. The status of BQ29400PW however is still active. Are there any plans to put BQ29400PW on EOL?

Hi Shibin,
Yes, the LDO is disabled during ship mode. If the MCU is powered by the BQ76920 send a boot pulse to TS1 to wake the BQ76920 which will power the controller. If the voltage of the cell stack is below VPORA the BQ76920 will not boot.
If the…

hi Max, We have a few gauges with integrated protection which you can look at. Like bq4050 or bq40z50-R3
If you prefer separate devices, I suggest you look at BQ2947 or BQ7718 for secondary protection ICs (OVP).
Can you let me know where you see this recommendation…

Hi Batt,
Thanks for the quick response. Not the answer I wanted, but it's probably the one I needed. I knew getting it to work the way I wanted would be more time consuming than just getting it to work right. I updated the diagram, should I include…
Thanks so much Matt.
BQ4050 and BQ40z50 might be perfect for what we need!
