U6268B General Description
The U6268B is an interface IC for remote automotive sensors. It links the crash sensors in the driver- and passenger door with the main airbag unit in the dashboard. Two identical channels supply the external sensors and receive digital information from them via one active wire each. The interface supplies the external sensors with a pre-regulated smoothed voltage, the external units transmit the digital information back to the interface by current modulation.
As the device is for safety critical applications, highest data transmission security is mandatory. With high immunity against cross-coupling between the two channels, the U6228B is tailored for the harsh automotive environment.
