Fault Protected High-Speed CAN FD Transceiver with Standby Mode
The NCA1042B is a high-speed CAN transceiver that provides an interface between a Controller Area Network (CAN) protocol controller and the physical two-wire CAN bus. The NCA1042B implements the CAN physical layer as defined in ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5. This implementation enables reliable communication in the CAN FD fast phase at data rates up to 5 Mbit/s. The NCA1042B provides thermal protection and transmit data dominant time out function.
