1.3
The CIC61508 is a Companion Safety Monitor Chip to build up functional safety
applications; examples include airbag, Electrical Powered Steering (EPS) and damping
systems. The chip is responsible for monitoring the host microcontroller’s behaviour. It
can monitor the host microcontroller’s power supply and verify the host microcontroller’s
requests. It therefore serves as an independent diagnostic monitoring device to allow the
host microcontroller system to be SIL3 approved.
