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.
