Description
The device 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.
Features
- 8 deployment drivers with SPI selectable firing current and times.
- Capability to deploy the squib with 1.2 A (min)/2 ms, 1.75 A (min)/1.0 ms and 1.75 A (min)/0.65 ms between VRES of 7 V to 37 V.
- Capability to deploy the squib with 1.5 A (min)/2 ms between VRES of 7 V to 25 V.
- Firing capability to deploy all channels simultaneously.
- Independently controlled high-side and lowside MOS for diagnosis.
- Analog output available for resistance measurement.
- Squib short.
