TLE7734G

The TLE7734 is intended to be used in an Automotive Restrain control module. The device allows individual control of up to four squib devices in CrosSaveTM standard configuration. It provides also a communication solution with a Master μC device (MCU) via a 16-Bit full duplex 8 MHz SPI interface. The IC is equipped with the required hardware to avoid or enable deployment as well as provide a full list of diagnostic functions.
