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
