L9658 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.
L9658 Key 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
- 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 4 satellite sensors
- Programmable independent current trip points for each satellite channel
- Support Manchester protocol for satellite sensors
- Supports for variable bit rate detection
