The MAX14882 isolated high-speed CAN transceiver improves 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 of the transceiver. Isolation improves communication by breaking ground loops and reduces noise where large differences in ground potentials exists between ports. The MAX14882 provides up to 5000VRMS (60s) of galvanic 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).
Interfacing with CAN-protocol controllers is simplified by the wide 3.0V to 5.5V supply voltage range (VDDA) on the controller-side of the device. The supply voltage range for the CAN bus-side of the device is 4.5V to 5.5V (VDDB). An integrated transformer driver and LDO can be used, with an external transformer, to generate the isolated supply for VDDB.
Field installation and troubleshooting are simplified by the polarity select (POL) input. POL swaps the functions of the CANH and CANL IOs, allowing for simple software correction of cross-wired bus cables in the field.
The MAX14882 operates over the -40°C to +125°C temperature range and is available in a 16-pin wide SOIC (W SOIC) package with 8mm of creepage and clearance.
