Product overview

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.
Diagnostic of squib driver and squib resistance measurement is controlled by micro controller.
Satellite interfaces support Manchester decoder with variable bit rate.
  • All 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 low-side 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) at 6.9 V VRES and 1.75 A at 12 V VRES
    • Interface with 4 satellite sensors
    • Programmable independent current trip points for each satellite channel
    • Support Manchester protocol for satellite sensors
    • Supports for variable bit rate detection
    • Independent current limit and fault timer shutdown protection for each satellite output
    • Short to ground and short to battery detection and reporting for each satellite channel
    • 5.5 MHz SPI interface
    • Satellite message error detection
    • Hall effect sensor support on satellite channels 3 and 4.
    • Low voltage internal reset
    • 2 kV ESD capability on all pins
    • Package: 64 leads LQFP
    • Technology: ST proprietary BCD5s (0.57 μm)
