  • RE: BQ76920: Designing BMS

    Resolved
    Hi Shibin, Yes, the LDO is disabled during ship mode. If the MCU is powered by the BQ76920 send a boot pulse to TS1 to wake the BQ76920 which will power the controller. If the voltage of the cell stack is below VPORA the BQ76920 will not boot. If the…

  • RE: BQ77915: BQ77915 combined with bq7716xy

    Resolved
    Hi Cedric, Yes, branch the circuits at the cells using individual filters of the this will give you the best separation of the 2 circuits. Be aware of common path resistance particularly if you are balancing since the BQ7716 will see the voltage of any…

  • BQ2947: 3.850 OV threshold

    TI Thinks Resolved
    Part Number: BQ2947 Other Parts Discussed in Thread: BQ7716 Hi, Team, My customer is requesting to prepare bq2947 with 3.850v OV threshold. But BQ7716 seems to have the same function as bq2947, and bq771605 with 3.850v OV threshold already exists. - What…

  • RE: BQ7718: external delay capacitance

    Hi Holger, I apologize, I believe that is a typo in our datasheet. The delay for the BQ7718 is internal and fixed. If you are looking for a similar device with a configurable delay, the BQ7716 may fit your needs.
