Octal squib driver and quad sensor interfaceASIC for safety application

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.
