Part Number: BQ77915 Tool/software: Kindly provide design formula for selecting current sense resistor, balancing resistor and gate resistor for BQ77915 Controller.
Hello Thomas,
Good day.
I have another question regarding the current limit range for the BQ77915. Is there any way to determine the exact value of the lowest current limit within the range? Additionally, are there any characteristics or graphs available…
Part Number: BQ77915 Tool/software: I've got a client who wants a battery-powered system to have a rocker power switch and a software shutdown process, and I'm hoping to use the BQ77915's CTRD input to force the DSG relay off when the system is supposed…
Part Number: BQ77915 Tool/software: Hello Iam using BQ77915 to balance cells in a 3 cell battery. When one of the Cell voltage goes below Under Voltage (2.7V), the discharge FET driver line goes low, but when the Cell voltage goes above UV + V hysterisis…
Part Number: BQ77915 Other Parts Discussed in Thread: BQ76200 , BQ76922 , BQ77307 Tool/software: Can you suggest how to convert low-side switching of bq77915 to high-side switching using bq76200.
Part Number: BQ77915 Tool/software: I tested cell balancing for 3cell with cell voltages 3.0V, 3.8V and 2.5V. The charging was stope at 11V. After charging the cell voltages are 3.5V,4.0V, and 3.5V. why it is not charging to Vfc. Is cell balancing is…
Part Number: BQ77915 Tool/software: Hello E2E Experts,
God day.
I would greatly appreciate it if you could review the attached schematic for any necessary corrections or improvements. The schematic is attached to the next message in PDF format with the…
Part Number: BQ77915 Tool/software: I am encountering an issue during the discharging phase. The charging MOSFET does not turn ON when discharging. I connected a 600mA load and also applied a transient load of 1A.
How it is detecting charger?
