Part Number: BQ40Z50 Other Parts Discussed in Thread: BQ2947 , BQ40Z60 , , BQ4050 Hi,
1、Is a secondary protection IC such as bq2947 is needed to work together with the gauge IC if the pack is 4S1P?
2、If the pack wants to communicate with a charger, and the…
Part Number: BQ2947 Other Parts Discussed in Thread: BQ40Z50 , I would like to combine two 3s2p Li-ion packs to make one 3s4p pack. Each of the 3s2p packs utilize the BQ2947 for over-voltage protection and both use the BQ40Z50 to balance cells. If I start…
Part Number: BQ2947 Hi,
I asked the question below, but I organize the contents and ask again.
e2e.ti.com/.../602746 Looking at the data sheet in Figure 9, after OV is detected, the capacitor connected to the CD pin starts charging. However, it seems that…
Part Number: BQ2947 Hi,
I am using bq 294702. Please tell me about the following contents. 1. About detection of OV. If the cell voltage exceeds VOH even once, is the overvoltage detection counter cleared when it falls below VOH (4.30 V)? Or is it when…
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…
Other Parts Discussed in Thread: BQ2947 Hi,
I wish to prototype a circuit using the BQ2947 secondary protection over voltage detector. This comes only in a WSON package. the problem is that I cannot find an adaptor PCB that will enable me to evaluate it…
Part Number: BQ77216 Other Parts Discussed in Thread: BQ2947 , Dear team, Do you have any comparison charts or documents for the product features and functions of BQ77216, BQ779X5, and BQ2947?
Part Number: BQ40Z60 Other Parts Discussed in Thread: BQ2947 , What's the polling frequency of the voltage sensing pin?
we use two OV protection chip, one is BQ40Z60, another one is BQ2947, we want to know the polling frequency of them.
