Key Products
As concern and legislation for driver and passenger safety continues to increase, airbags have become a standard feature in motor vehicles from small city cars to luxury SUVs.

A range of scalable solutions

Automakers need  a range of scalable solutions that are feature- and cost-optimized – yet meet the highest reliability standards – for the different models in their range - from entry-level  vehicles to extremely complex solutions, with an increasing number of squib ICs (for airbag deployment) and acceleration satellite sensors (intelligent crash sensors),  to provide extensive  features for Premium vehicles.

Our offer that includes SPC5 32-bit automotive microcontrollers, power supply modules, efficient boost and buck converters, and accurate ADC voltage references. We also have  squib drivers with relative diagnostics and programmable deployment profiles and PSI5 satellite sensor interfaces.
