MAX14878WAWA+

Drivers, Receivers, Transceivers Overview

The MAX14878WAWA+ is a high-speed isolated CAN transceiver providing up to 5000VRMS galvanic isolation between the controller side and the CAN bus. It supports data rates up to 1Mbps with a wide supply voltage range of 1.71V to 5.5V on the controller side (VDDA) and 4.5V to 5.5V on the bus side (VDDB). The device features ±25V common-mode input range, ±54V fault protection, and ±15kV ESD protection on the bus lines. It operates over a temperature range of -40°C to +125°C in an 8-pin wide SOIC package.

Drivers, Receivers, Transceivers Feature Summary

• Integrated galvanic isolation barrier breaks ground loops and reduces noise in environments with large ground potential differences.
• Robust communication enabled by ±25V receiver input common-mode range and ±54V fault tolerance on bus lines.
• Dominant timeout protection prevents erroneous controllers from clamping the bus to a dominant level continuously.

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and isolation rating. Ensure compatibility with system voltage requirements and thermal management needs before procurement. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Drivers, Receivers, Transceivers Selection Notes

Select this component when high-voltage isolation is required for CAN networks with significant ground potential differences. The 8-pin wide SOIC package offers 8mm creepage distance. Note that this specific variant lacks a standby input; consider the MAX14879 or MAX14880 if low-power standby modes are necessary for the application design.

Drivers, Receivers, Transceivers Part Context

This device belongs to the MAX14878–MAX14880 family of isolated CAN transceivers manufactured by Analog Devices / Maxim Integrated. The family includes variants with different isolation voltages and standby capabilities. The MAX14878WAWA+ specifically denotes the 5kVRMS isolation version in the 8-pin wide SOIC package without a standby pin.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX14878AWA+ provides 3.5kVRMS isolation in the same package. The MAX14878AWE+ offers 5kVRMS isolation but uses a 16-pin W SOIC package. For designs requiring a standby input, the MAX14879AWE+ or MAX14880AWE+ are functional alternatives within the same family.
