Analog Devices MAX14882

Description

The MAX14882 isolated high-speed CAN transceiverimproves communication and safety by integrating galvanic isolation between the CAN-protocol controller-side (TDX, RXD) of the device and the physical wires of the CAN network (CANH, CANL) cable-side/bus-side ofthe transceiver. Isolation improves communication bybreaking ground loops and reduces noise where largedifferences in ground potentials exists between ports.The MAX14882 provides up to 5000VRMS (60s) ofgalvanic isolation and a continuous working voltage of up to 848VRMS, while operating at the maximum high-speed CAN data rate of 1Mbps.The MAX14882 features additional integrated protection for robust communication. The ±25V receiver input common-mode range exceeds the ISO 11898 specification requirement of -2V to +7V. Additionally, the CANH and CANL IOs are fault tolerant up to ±54V and are protected from electrostatic discharge (ESD) up to ±15kV to GNDB on the bus-side, as specified by the Human Body Model (HBM).
