Airbags have been a standard feature in passenger cars for over 20 years. Naturally these systems need to be extremely robust and reliable, regardless of whether it is just a single airbag for the driver and front passenger or a complete multi-stage airbag system offering a range of protection options (front, side, head, rollover and even pedestrian protection). A Safing MOSFET in series with firing circuit transistors provides cost-effective operational reliability, enabling breakage of the current circuit in case of incorrect operation due to malfunction or electrical noise.
