Part Number: BQ77915 Tool/software: Hi Team,
We have developed 12V BMS using BQ7791506 for 40AH Starter Battery in Vehicle. But during Cranking, the BMS is not allowing required Cranking Current. So that we tried to change current resistors ( presently…
Part Number: BQ77915 Tool/software: Hello Team,
I am design the battery pack for Lifepo4 cell, 14.6V Max
I am creating the OV condition as mention in the EVAL kit user guide with 4 series resistors.
1. I can able to create the undervoltage (Less than…
Part Number: BQ77915 Tool/software: I am requesting the models because I need them for a signal integrity analysis in Altium. The project consists of a PCB for a Battery Management System. This analysis will help us decide which of the two designs we…
Part Number: BQ77915 Tool/software: Hello,
In my 4S battery charger design, I am using the BQ7791500 IC and a PMOS charger FET as described in the datasheet.
Could you suggest suitable PMOS, NPN, and NMOS components for this design?
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: Hello all
I am using BQ77915 IC for cell balancing in a three cell battery.
I selected 3 cells whose voltages were 3.66V, 3.65V and 3.59V for charging.
I am using external MOSFETS as per the recommended circuit in datasheet…
Part Number: BQ77915 Tool/software: Hi,
I would like to ask about circuit for MOSFET at charging side and discharging side. Sense resistor(2mR) is implemented to ensure max 30A Load. Due to the Heat dissipation issue. Hence, I have decided to put 2 mosfet…
