Part Number: BQ2947 Hi Guys,
in the the datasheet is written that the bq2947 covers a OPV range from 3.85V to 4.6V and one has to select the desired OVP by choosing the correct suffix of the partnumber (for example bq2947 07 for 4.225V).
My problem is…
Part Number: BQ2947 Hello,
Do you advice and tips regarding the use of P-Mosfet instead of triggered fuse (SFH-xxx) with BQ2947? This kind of fuse is not easily available and we have some false triggering when connecting the cells together to form the…
Part Number: BQ2947 Hi,

Hi Shirish,
can you tell me more in detailes about the differences between bq40z50 and bq40z60?
If the pack wants to communicate with a charger, and the charger also has a TI charge IC, which is the better gauge IC bwtween bq40z50 and bq40z60?
Is…
Part Number: BQ2947 Other Parts Discussed in Thread: TIDA-00108 Hello,
I have used the bq2947 part successfully on a 4s pack as a secondary over-voltage protection. I am in the process of developing a 7s pack but didn't see any components that perform…
