ST L9680TR

汽车级SPI5.5V表面贴装型

Overview

The L9680TR is an advanced airbag system chip solution targeted for mature airbag market and integrated safety markets. This device is family compatible with the L9678 and L9679 devices. Safety system integration is enabled through higher power supply currents and integrated active wheel speed sensor interface. The active wheel speed interface is shared with the PSI-5 satellite interface to create a generic remote safety sensor interface compliant to both systems.
