L9965P-FN-TR

Single channel pyro switch driver for HV battery disconnect

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

L9965P is an automotive-grade single channel pyro-fuse driver capable to break high voltage battery line quickly and reliably in case of short circuit or car crash.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...

Key features
  • AEC-Q100 grade 1 qualified
  • Full ISO26262 compliant, ASIL-D systems ready
  • 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-selectable FIRE_GOOD signal
  • Embedded NVM for configuration parameters storage and runtime configuration integrity check
  • Easy integration with L9965C companion CSA, implementing many of the safety mechanisms needed to achieve ASIL targets, thus allowing easy L9965P 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/L9965C interface
  • Compatible with pyro-fuses certified according LV-16 and USCAR-28
