TLE6714G

The TLE6714G is a 4 loop firing IC specially designed for automotive restraint applications. The device, located in the ECU (Electronic Control Unit) of the airbag system, provides four independent actuator channels for firing loops. Each channel is equipped with various diagnostic functions. Communication between the μC and TLE 6714G is performed via SPI and analog/digital interface pins.
