Airbag systems

Airbag system ICs combine all peripheral system functions of an airbag system in one single chip: digital crash sensor interfaces, firing loop drivers, extensive safety and diagnosis mechanisms and the power supply for the entire system.

In addition, Bosch offers ICs for dedicated functions like firing loop drivers, digital sensor interfaces and others.
