Part Number: BQ26221 Other Parts Discussed in Thread: BQ28Z620 , BQ35100 Hi Team
My customer wanna using a coulomb counter to achieve charge and discharge count at the board side, not in the battery pack.
They choose the BQ26221 as the solution, but I noticed…
Part Number: BQ26221 Other Parts Discussed in Thread: BQ2060 Dear team,
Customer is looking for a gauge for 1cell NiMH battery, could you suggest if BQ26221 is the suitable recommendation for this application? Or do we get any more suitable parts for…
Other Parts Discussed in Thread: BQ26221 Hi

Other Parts Discussed in Thread: BQ26221 Hi,
I have the datasheet SLUS607, may 2004 for the BQ26221.
On page 8, it mentions the charge counter count at a rate of 3.0uVH per unit. it states that for one hour, a 24.42 mV signal produces 8000DCR.
how do…

Other Parts Discussed in Thread: OMAP3530 , BQ26221 Hi,
It seems there is a mistake in the OMAP3530 datasheet concerning HDQ timings.
On page 230, it states tHW0 to be at 180us minimum, should not it be 180us MAXIMUM ?
anyway, can someone confirm…
Other Parts Discussed in Thread: BQ2060A , BQ26500 , BQ26501 Hello Everybody,
I am designing a new DC-UPS with external batteries, and I'd like to keep track of their SOC. Some of those batteries (LiFePO4, LiCoO2) will have a BMS with integrated bq4…

Mike,
MikeV said: The Vss of the gauge is connected typically to the negative node of the cell. Pack- is the the most negative reference that the connecting system has access to.
If PACK- is the most negative reference a connecting system can access…
