The airbag firing chip is a dedicated driver chip to drive the airbag module for the safety airbag controller. Key features include:
1. Providing embedded power supply to microcontrollers, central sensors, and energy storage capacitors.
2. Supporting 6 PSI5 interfaces.
3. Supporting a safety controller for microcontroller monitoring.
4. Supporting 16 firing loops.
5. Supporting automatic diagnosis and resistance or Hall element detection paths.
Airbag Firing Chip（CCL1600B） can constitute a safety airbag controller with a microcontroller. The advantages of CCL1600B are as follows:
1．Supporting multiple series of microcontrollers.
2．Supporting embedded CAN/CANFD transceivers (for some models).
3．Supporting multiple LDO power supply, including one controllable 3.3V power.
