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.

8 deployment drivers sized to deliver 1.2 A (min) for 2 ms (min) and 1.75 A (min) for 1 ms (min)
Independently controlled high-side and low-side MOS for diagnosis
Analog output available for resistance
Squib short to ground, short to battery and MOS diagnostic available on SPI register
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
