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.
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
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 when the low
side MOS is shorted to ground
• 2 fire enable inputs
• 5.5 MHz SPI interface
• Low voltage internal reset
• 2 kV ESD capability on all pins
• Package: LQFP64
• Technology: ST proprietary BCD5 (0.65µm)
• RoHS compliant
