L9965P-FP中文资料意法半导体数据手册PDF规格书

特性 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
