U6268B Datasheet Side-airbag Sensor Dual Interface

Manufacturer: Atmel (now Microchip Technology)

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.

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-compatible Input Activates the Sensor Data Output Can be Directly Connected to a Microcontroller Input Operation Supply Voltage Range 5.7V ≤ VS ≤ 40V ESD Protection According to MIL-STD-883.
