NCV7446 is two channel physical layer device using the Controller Area Network (CAN) protocol. It allows interfacing of two independent CAN physical buses and two independent CAN protocol controllers. The transceivers provide differential transmit capability to the bus and differential receive capability to the CAN controllers.It is consisted of two totally independent NCV7344 transceivers.The NCV7446 guarantees additional timing parameters to ensure robust communication at data rates beyond 1 Mbps to cope with CAN flexible data rate requirements (CAN FD). These features make the NCV7446 an excellent choice for all types of HS−CAN networks, in nodes that require a low−power mode with wake−up capability via the CAN bus.
