The UMCAN1472N 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 transceiver is designed for high-speed CAN applications in the automotive industry, providing the differential transmit and receive capability to (a microcontroller with) a CAN protocol controller.

The UMCAN1472N offers improved ElectroMagnetic Compatibility (EMC) and ElectroStatic Discharge (ESD) performance, and also features:

• ±70V Bus Fault Protection

• Ideal passive behavior to the CAN bus when the supply voltage is off

• A very low–current Standby mode with bus wake–up capability

• Excellent EMC performance, even without a common mode choke

The UMCAN1472N transceiver implements the CAN physical layer as defined in ISO 11898-2:2024 third edition and SAE J2284-1 to SAE J2284-5, and is fully interoperable with high-speed Classical CAN and CAN FD transceivers. The UMCAN1472N includes CAN signal improvement capability (SIC), as defined in ISO 11898-2:2024 parameter set C. CAN signal improvement significantly reduces signal ringing in a network, allowing reliable CAN FD communication to function in larger topologies. In addition, the UMCAN1472N features a much tighter bit timing symmetry performance to enable CAN FD communication up to 8 Mbit/s. These features make the UMCAN1472N an excellent choice for all types of HS-CAN networks, in nodes that require a standby mode with wake-up capability via the bus.
