Part Number: BQ77915 Tool/software: Kindly provide design formula for selecting current sense resistor, balancing resistor and gate resistor for BQ77915 Controller.
Part Number: BQ77915 Tool/software: I'm working on a system that is powered by two batteries in parallel, with each battery having 3 cells in series. If I have balancing leads for each cell in each battery, can I wire both of them to the same BQ77915…
Part Number: BQ77915 I have used the following while designing
Part BQ7791502
Use only 3S cells.
Charging voltage upto 4.1V/cell and 12.3V for the pack from the charger IC
Discharging current will be 4A
Balancing: Internal
U42 will be the balancing …
Part Number: BQ77915 Tool/software: this is a new thread in continuation of this one: (+) BQ77915: Charging only up to 4,0V, No Balancing observable - Power management forum - Power management - TI E2E support forums since the old problem is resolved so…
Part Number: BQ77915 Tool/software: Hi,
My design with the BQ77915 is the following. I am not using the CHG and DSG option, just the balancing;
I am observing strange behaviour on CHG pin (DSG is also always low..).
I am not using temp sensor, so…
Part Number: BQ77915 Tool/software: Hi, i have a problem with the BQ7791501.
When the battery reachs the undervoltage threshold, DSG FET turns off, while CHG FET stays on.
While this happen, i have a load current of 2 mA which is way too much for this…
Part Number: BQ77915 Tool/software: Hi,
In the datasheet of the BQ77915, I find the indication for the TS pin when function is not used unclear :
"Thermistor measurement input. Connect a 10-kΩ resistor to the VSS pin if the function is not…
