STMicroelectronics L9662
The device is intended to deploy up to 8 squibs and to interface up to 4 satellites.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 to ground, short to battery and MOS diagnostic available on SPI register
● Capability to deploy the squib the low side MOS is shorted to ground
● 4 Fire enable inputs
● Interface with 4 satellite sensors
● Programmable independent current trip points for each satellite channel
● Support Manchester 1 or 2 protocol for satellite sensors
● Support PSI5 (Parity) protocol for satellite sensors (reference PSI5 technical specification V 1.2 /14.06.07)
● Support for Sync pulse and minibus for satellites
● Supports for var...
