The L9679E is an extension chip in airbag systems or a pyroswitch manager. This device is family-compatible with the L9679 and L9680 devices. The device includes an octal driver for squib/pyroswitch deployments and a quad channel interface for PSI-5 sensors. Deployment profiles can be set according to user specifications via SPI configuration, as well as the protocol to be used to communicate with the satellite sensors. Independent configurable arming inputs are provided for a programmable mapping of the loops to be deployed.
