MLX81100
LIN Slave for FET Control
3.4 Connection to External CAN Controller
If the application requires a connection to the CAN network it can be realized with the help of an external
CAN communication CPU. The following circuitry shows a sample how to implement this together with our
MLX81100.
The communication between MLX8100 and external CAN controller is done via the SPI interface of the
MelexCM.
A bus wake-up will be signalised at the INH pin of the CAN transceiver. This signal will be used from a
normal HV-IO pin to wake-up the MLX81100.
