  • BQ7716: Overvoltage event detection/qualification/triggering of chemical fuse blow

    John Wright
    John Wright
    Resolved
    Part Number: BQ7716 I am uncertain of the overvoltage hysteresis parameter and its interaction with the "tdelay" parameter as used in the BQ7716x parts. For simplicity, assume the BQ771600 (4.3V overvoltage threshold) is monitoring a single…

    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…

    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…

    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.
