Product overview
Description
L9654 is intended to deploy up to 4 squibs and to interface up to 2 satellites.
Squib drivers are sized to deploy 1.2 A (min.) for 2 ms (min.) during load dump and 1.75 A (min.) for 1 ms (min.) during load dump.
Diagnostic of squib driver and squib resistance measurement is controlled by micro controllers.
Satellite interfaces support Manchester decoder with variable bit rates.
