L9658 Datasheet Octal Squib Driver And Quad Sensor Interface Asic

Manufacturer: STMicroelectronics

Overview: L9658 Octal squib driver and quad sensor interface ASIC for safety.

General Description

L9658 is intended to deploy up to 8 squibs and to interface up to 4 satellites.

2 satellite interfaces can be used to interface Hall sensors.

Squib drivers are sized to deploy 1.2 A minimum for 2 ms minimum during load dump and 1.75 A minimum for 1ms minimum during load dump.

Key Features

  • 8 deployment drivers sized to deliver 1.2 A (min) for 2 ms (min) and 1.75 A (min) for 1 ms (min).
  • Independently controlled high-side and lowside MOS for diagnosis.
  • Analog output available for resistance.
  • Squib short to ground, short to battery and MOS diagnostic available on SPI register.
  • Capability to deploy the squib with 1.2 A (min) or 1.75 A under 35 V load-dump condition and the low side MOS is shorted to ground.
  • Capability to deploy the squib with 1.2 A (min.
