L9659 Octal squib driver ASIC for safety application
The L9659 is intended to deploy up to 8 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
