MAX14879AWE+T

Drivers, Receivers, Transceivers Overview

The MAX14879AWE+T is an isolated CAN transceiver providing up to 2.75kVRMS galvanic isolation between the controller and bus sides. It supports data rates up to 1Mbps with a wide 1.71V to 5.5V supply voltage range on the controller side (VDDA) and 4.5V to 5.5V on the bus side (VDDB). The device features an integrated standby input for low-power operation, ±25V receiver common-mode range, and ±54V fault protection. ESD protection reaches ±15kV on the bus side. It operates from -40°C to +125°C in a 16-pin Wide SOIC package.

Drivers, Receivers, Transceivers Feature Summary

• Integrated galvanic isolation breaks ground loops and reduces noise
• Standby input enables low-power mode by disabling the driver
• Wide receiver common-mode range and fault tolerance ensure robust communication
• Dominant timeout protection prevents erroneous bus clamping

Drivers, Receivers, Transceivers Applications

• Industrial Controls
• HVAC Systems
• Building Automation
• Switching Gear

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific part number against official manufacturer documentation to confirm isolation ratings and package type. Ensure compatibility with system voltage requirements and temperature ranges before integration. Cross-reference ordering information to validate production status and availability through authorized channels.

Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed CAN communication requires significant potential differences between grounds. The integrated standby feature makes it suitable for power-sensitive applications. Verify that the 2.75kVRMS isolation rating meets safety standards for the specific application environment compared to higher-rated alternatives.

Drivers, Receivers, Transceivers Part Context

This device belongs to the MAX14878–MAX14880 family of isolated CAN transceivers. While sharing similar interfaces and protocols, it differs from siblings like the MAX14878 or MAX14880 primarily in its lower 2.75kVRMS isolation rating and inclusion of a standby pin, unlike the non-standby MAX14878.

Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes within the same family include the MAX14878AWE+T and MAX14880AWE+T. Note that these alternatives offer 5kVRMS isolation but lack the standby input found in the MAX14879. Design changes may be required if the standby functionality is critical.
