Octal squib driver and quad Manchester/PSI5 encoded sensor interface ASIC for safety application

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.
