Product overview

Description

The L9659 is intended to deploy up to 8 squibs. Squib drivers are sized to deploy 1.2 A minimum for 2 ms, 1.75 A minimum for 1 ms and 1.75 A minimum for 0.65 ms during load dump along with 1.5 A minimum for 2 ms for VRES voltages less than 25 V.

Full diagnostic capabilities of the squib interface are provided.

  • All features

    • 8 deployment drivers with SPI selectable firing current and times
    • Capability to deploy the squib with 1.2 A (min)/2 ms, 1.75 A (min)/1.0 ms and 1.75 A (min)/0.65 ms between VRES of 7 V to 37 V
    • Capability to deploy the squib with 1.5 A (min)/2 ms between VRES of 7 V to 25 V
    • Firing capability to deploy all channels simultaneously
    • Independently controlled high-side and low-side MOS for diagnosis
