描述 Description

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.

特性 Features

·Four independent squib channels with high-side and low-side switch
·Four independent programmable deployment firing timer
·Digital inputs allow independent safing logic to prevent/enable deployment
·All digital I/O pins are 3.3 V and 5 V compatible
·16-Bit full duplex 8 MHz SPI
·Multiplexed analog output for signal monitoring

应用 Application

·Mid & High end Restraint systems
