L9662 Octal squib driver and quad Manchester/PSI5 encoded sensor interface ASIC

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. Squib drivers are sized to deploy 1.2 A minimum for 2 ms, 1.75 A minimum for 1 ms and 1.75 A minimum for 0.65 ms during load dump along with 1.5 A minimu.

L9662 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

* Fi
