Hi,
How is Over-temperature sensing working in this IC. I thought it would have been a simple voltage divider with supply voltage at VTB and sensing at TS. But it doesn't seems like it is working like this.
I…
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…
