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…
