Product overview

Description

The L9689E is an airbag extension chip, family compatible with L9691 and L9690 devices.

The IC includes eight deployment drivers, supporting both squib and low-energy actuator (LEA) loads (on two channels only). Additionally, it includes a two channels interface for PSI-5 remote sensors, a seven channels hall-effect/resistive sensor interface and two general purpose low-side driver outputs.

Dual SPI interfaces separate device global functions and remote sensors; all deployment loops are armed via snooping on the remote sensor SPI interface and an internal programmable mapping.
