Product overview

Description

The device 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, 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. Satellite interfaces support Manchester 1, 2 and PSI5 decoding with variable bit rate.
  • 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
    • Analog output available for resistance measurement
    • Squib short to ground, short to battery and MOS diagnostic available on SPI register
    • Capability to deploy the squib the low side MOS is shorted to ground
    • 4 Fire enable inputs
    • Interface with 4 satellite sensors
    • Programmable independent current trip points for each satellite channel
    • Support Manchester 1 or 2 protocol for satellite sensors
    • Support PSI5 (Parity) protocol for satellite sensors (reference PSI5 technical specification V 1.2 /14.06.07)
    • Support for Sync pulse and minibus for satellites
    • 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
    • 2 independent SPI interfaces
    • 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: LQFP64
    • Technology: ST Proprietary BCD5
