描述 Description

The UM3842 high–speed CAN transceiver 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 UM3842 offers improved Electro Magnetic Compatibility (EMC) and Electro Static Discharge (ESD) performance, and also features:
• Ideal passive behavior to the CAN bus when the supply voltage is off
• A very low–current Standby mode with bus wake–up capability
• UM3842S8 and UM3842DA can be interfaced directly to microcontrollers with supply voltages from 3V to 5V
The UM3842 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. These features make the UM3842 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.
