L9654 Overview
Squib short to ground, short to battery and MOS diagnostic available on SPI register L9654 is intended to deploy up to 4 squibs and to interface up to 2 satellites. Capability to deploy the squib with 1.2 A (min.) or 1.75 A under 35 V load-dump condition and the low-side MOS is shorted to ground Capability to deploy the squib with 1.2 A (min.) at 6.9 V VRES and 1.75 A at 12 V VRES. Interface with 2 satellite...
