MAX14882 5kV Isolated CAN Transceiver RMS with Integrated Transformer Driver General Description Benefits and Features The MAX14882 isolated high-speed CAN transceiver Integrated Protection for More Robust improves communication and safety by integrating gal- Communication vanic isolation between the CAN-protocol controller-side 5kV Withstand Galvanic Isolation (60s) RMS (TDX, RXD) of the device and the physical wires of the 25V Common Mode Range CAN network (CANH, CANL) cable-side/bus-side of 54V Fault Protection 15kV ESD (HBM) Protection on Driver Outputs/ the transceiver. Isolation improves communication by breaking ground loops and reduces noise where large Receiver Inputs differences in ground potentials exists between ports. High-Performance Transceiver Enables Flexible The MAX14882 provides up to 5000V (60s) of RMS Designs galvanic isolation and a continuous working voltage of up Wide 3.0V to 5.5V Supply Voltage Range for CAN to 848V , while operating at the maximum high-speed RMS Controller Interface CAN data rate of 1Mbps. Field Bus Polarity Control (POL) Integrated Transformer Driver for Power Transfer to The MAX14882 features additional integrated protection for Bus-Side robust communication. The 25V receiver input common- Integrated LDO for Powering CAN Bus-Side mode range exceeds the ISO 11898 specification requirement of -2V to +7V. Additionally, the CANH and CANL IOs are Safety Regulatory Approvals (Pending) fault tolerant up to 54V and are protected from electrostatic UL1577 (Basic Insulation) discharge (ESD) up to 15kV to GNDB on the bus-side, as cUL According to CSA Bulletin 5A specified by the Human Body Model (HBM). Ordering Information appears at end of data sheet. Interfacing with CAN-protocol controllers is simplified by the wide 3.0V to 5.5V supply voltage range (V ) on the DDA controller-side of the device. The supply voltage range for Simplified Block Diagram the CAN bus-side of the device is 4.5V to 5.5V (V ). An DDB integrated transformer driver and LDO can be used, with an external transformer, to generate the isolated supply 3.3V for V . DDB 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 TD1 TD2 V LDO correction of cross-wired bus cables in the field. V DDB XFMR V DDA 5V LDO The MAX14882 operates over the -40C to +125C DRIVER temperature range and is available in a 16-pin wide SOIC POL (W SOIC) package with 8mm of creepage and clearance.
