Side-Airbag Sensor Dual Interface
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 U6268B is tailored for the harsh automotive
environment.
Features
Two identical interface channels
Provides a pre-regulated smoothed voltage and a
supply current up to 50 mA for the sensors
Receives data from the sensors by current modulation
with a transmission rate of 60 kBaud (transmission
bandwidth 500 kHz)
Current modulation provides high noise immunity for
data transfer
TTL-compatible input activate the sensor
Data output can be directly connected to a micro-
controller input
