Description

Packing

Tray

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.
