U6268B Overview
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.
U6268B Key Features
- Two Identical Interface Channels
- Pre-regulated Smoothed Voltage and a Supply Current up to 50 mA for the Sensors
- Data from the Sensors by Current Modulation with a Transmission Rate of 60 kBaud
- (Transmission Bandwidth 500 kHz) TTL-patible Input Activates the Sensor Data Output Can be Directly Connected to a Micro
- Simple Wiring Thanks to One mon Line for Supply of the Sensor and Data
- Current Modulation Provides High Noise Immunity for Data Transfer
