Part Number: BQ77905 Hi Support team,
has anybody a simple excel table with temperature thresholds of BQ77905 to optimize temperature behavior? US customer of 500k BMS like to get a 75°C cut off with just 5°C hysterese for optimal operation, so different…
Part Number: BQ77905 Good Afternoon,
We are currently experiencing an issue with a new design utilizing a BQ7790509 and a BQ294700DSGR. Once assembled, we are able to discharge and charge the pack without issue. However, once the first protection has been…
Part Number: BQ77905 Dear TI expert,
Currently i am use BQ77905 design one BMS, i use low temperature LiFePo4 cell, i want to under temperature -10 to protect and over temperature 55 to protect, but RTS_PU meet -10 under temperature protector, but can…
Part Number: BQ77905 Hi all,
I'm planning to use the BQ7790512 for a 3S battery configuration. I don't want to use the load detection function as the batteries and the IC will be in an enclosure, instead we will rely on the delays. From the datasheet…
Part Number: BQ77905 Other Parts Discussed in Thread: BQ76952 Hi,
I have 4S* 3.0V EDLC charge protect application. Needs charge from 0V to 10.95V(2.73V for each).
Charge current ~10A, maximum discharge current ~50A.
Does BQ77905 suitable for this application…
Part Number: BQ77905 I use the BQ7790508 in my design. I found that the under voltage level is 2.5V, not as data sheet claim 2.0V.
But the over voltage level is correct to 3.9V.
I had test a few units and they both have the same issue.
I have follow…
Part Number: BQ77905 Other Parts Discussed in Thread: BQ7718 1. Do we have 2s primary battery protector products?
2. Whether BQ77905 could be used in the 2s battery situation?
Part Number: BQ77905 Other Parts Discussed in Thread: INA381 I just inherent a BMS design using BQ775905. The battery pack use 0.1mR shunt so the over current protection can not be used directly on the BQ77905. The previous designer decided to short out…

Hi
Please help check the schematic, the problem is VTB PIN, CHG,DSG no output voltage. We have connected the10K NTC.
We do not need the current sense function. The LD pin is connected to the ground. the schematic not show this modify…
