CF190 | PSI5 interface for digital satellite sensor

Up to 4 sensors per channel in PSI5 bus mode

CF190 provides two PSI5 (V1.3) channels for connecting airbag crash sensors to the system's microcontroller.

Each channel can be set to point-to-point mode (one sensor) or bus mode (max. four sensors).

CF190 provides power to satellite sensors and serves as digital communication interface between microcontroller and sensor.
