MAX14882  
5kV  
Isolated CAN Transceiver  
RMS  
with Integrated Transformer Driver  
General Description  
Benefits and Features  
● Integrated Protection for More Robust  
The MAX14882 isolated high-speed CAN transceiver  
improves communication and safety by integrating gal-  
vanic 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.  
Communication  
• 5kV  
Withstand Galvanic Isolation (60s)  
RMS  
• ±25V Common Mode Range  
• ±54V Fault Protection  
• ±15kV ESD (HBM) Protection on Driver Outputs/  
Receiver Inputs  
● High-Performance Transceiver Enables Flexible  
Designs  
The MAX14882 provides up to 5000V  
galvanic isolation and a continuous working voltage of up  
(60s) of  
RMS  
• Wide 3.0V to 5.5V Supply Voltage Range for CAN  
Controller Interface  
• Field Bus Polarity Control (POL)  
• Integrated Transformer Driver for Power Transfer to  
Bus-Side  
to 848V , while operating at the maximum high-speed  
RMS  
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).  
• Integrated LDO for Powering CAN Bus-Side  
● Safety Regulatory Approvals (Pending)  
• UL1577 (Basic Insulation)  
• cUL According to CSA Bulletin 5A  
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  
the CAN bus-side of the device is 4.5V to 5.5V (V ). An  
Simplified Block Diagram  
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  
correction of cross-wired bus cables in the field.

temperature range and is available in a 16-pin wide SOIC  
(W SOIC) package with 8mm of creepage and clearance.
