MAX14882AWE+T

Drivers, Receivers, Transceivers Overview

The MAX14882AWE+T is a high-speed isolated CAN transceiver in a 16-pin wide SOIC package. It provides 5000V RMS galvanic isolation between the controller-side (3.0V to 5.5V) and bus-side (4.5V to 5.5V). The device supports data rates up to 1Mbps with propagation delays of 80ns for TXD and 135ns for RXD. Integrated features include an LDO, transformer driver, ±54V fault protection, and ±15kV HBM ESD protection. Operating temperature ranges from -40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated galvanic isolation breaks ground loops and reduces noise.
• Built-in transformer driver and LDO simplify power supply design.
• Polarity select input allows software correction of cross-wired cables.
• Robust communication ensured by wide common-mode range and fault tolerance.

Drivers, Receivers, Transceivers Procurement Notes

Verify the 'T' suffix indicates tape and reel packaging rather than tube. Confirm RoHS compliance status via official documentation. Ensure the specific variant matches the required isolation voltage and operating temperature range for the target application environment.

Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed CAN communication requires robust isolation against ground potential differences. The integrated power transfer capabilities reduce external component count. Verify that the 16-pin wide SOIC footprint fits the PCB layout constraints and thermal requirements.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX14882 series of isolated CAN transceivers. It shares core functionality with the MAX14882AWE+, differing primarily in the 'T' suffix which denotes tape and reel packaging for automated assembly processes.

Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes within the same family include the MAX14882AWE+. Verify pinout compatibility and electrical specifications before swapping packages or variants.

Drivers, Receivers, Transceivers FAQ

What is the function of the POL input?

The POL input swaps the functions of the CANH and CANL IOs, allowing for simple software correction of cross-wired bus cables in the field.

How is power transferred across the isolation barrier?

Power is transferred using an integrated transformer driver that drives an external center-tapped transformer, along with an internal LDO to regulate the bus-side supply.

What is the dominant timeout feature?

The transmitter-dominant timeout releases the bus to a recessive state if TXD remains low for longer than tDOM, preventing erroneous controllers from clamping the bus.
