L9660 Datasheet Quad Squib Driver Asic

Manufacturer: STMicroelectronics

Overview: L9660 Quad squib driver ASIC for safety application Datasheet - production data '!0'03 LQFP64 (10x10x1.

General Description

The L9660 is intended to deploy up to 4 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.

Key Features

  • 4 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 lowside MOS for diagnosis.
  • Analog output available for resistance measurement.
  • Squib short.
