TLE 7729

4 Channel Airbag Satellite Receiver IC

SatRIC

designed for automotive restraint applications. The device, located in the eCU

(electronic Control Unit) of the airbag system, is able to receive data from different

types of intelligent sensors like inertia and pressure sensor satellites for front-,

side-, or rear-crash sensor applications. It provides a pre-regulated power supply

voltage to the satellites over a twisted pair of wires. The satellite module transmits

digital data to TLe 7729 by modulating the line current.
