  • BQ76972: BQ76972 reconfigurable 4S–16S hardware without solder jumpers or 0 Ohm resistors

    TI Thinks Resolved
    Part Number: BQ76972 Hello, I am designing a battery management system using the BQ7697202PFBR. The same fully assembled BMS PCB must be usable with battery packs containing any number of series-connected cells from 4S to 16S. The number of cells…

  • BQ76972: BQ76972 VREG1 Unstable Output Causing MCU Wake-Up Failure

    Part Number: BQ76972 Other Parts Discussed in Thread: LM5164 Hello, I am currently developing a BMS using the BQ76972 device. I am using the VREG1 output (3.3V) from the BQ76972 to supply power to an external MCU. However, when I observe the VREG1…

  • BQ76972-Q1: BQ76972 — LD Pin Load Detect readings don't scale linearly with load resistance, and values fluctuate significantly

    Part Number: BQ76972-Q1 Setup: DSG pin unused (FETs are controlled by an external gate driver, not the FAE directly) LD pin tied to PACK+ through a 10kohm series resistor, per the datasheet's unused pin recommendation, to keep load detect functional…
