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.
Features
- 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 lowside 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.
