    L99BM2P-FN-TR

    Single channel pyro switch driver for HV battery disconnect

    Parameters
    ECCN USEAR99
    ECCN EUNEC
    Packing TypeTape And Reel
    RoHs compliantEcopack2
    GradeIndustrial
    Package NameVFQFN 5X5X0.9 32+4L WETT. FLANKS
    Description

    L99BM2P is a single channel pyro-fuse driver capable to break high voltage battery line quickly and reliably in case of short circuit.To accomplish this function, the device features a dual FET output stage made of a HS and a LS powerMOS. The stage is equipped with a closed loop current feedback...

    Key features
    Key features
    • Very low power consumption:
      • Less than 10 μA in deep-sleep mode (only trigger detection enabled)

      • Less than 4 mA in low-power mode (trigger detection enabled, ER boost recharge active, cyclic diagnostics every 100 ms)
    • Boost regulator to charge Energy Reserve (ER) with bang-bang control to reduce consumption
    • FENH/FENL digital input triggers, compatible to level or PWM signals (16 kHz and 125 kHz), with line integrity check feature
    • Autonomous cyclic diagnostic routine to ensure detection of all failures which may prevent safe deployment and/or cause inadvertent deployment
    • Programmable deployment profile: current value and time duration can be adapted to different pyro-fuse igniters
    • Firing strategy supporting multiple retry attempts based on user-selectabl
    • FIRE_GOOD signal
    • Embedded NVM for configuration parameters storage and runtime configuration integrity check
    • Easy integration with L99BM2C companion CSA, implementing many of the safety mechanisms, thus allowing easy L99BM2P plug and play in the system
    • Pyro-fuse deployment available down to a minimum operating battery voltage of 6 V
    • 24-bit peripheral SPI for direct MCU/L99BM2P interface
    • Compatible with pyro-fuses certified according LV-16 and USCAR-28
