ADM3120BX-AB-T-2-G

Overview

The ADM3120BX-AB-T-2-G is a high-speed, isolated CAN transceiver manufactured by Infineon Technologies. It integrates an isolated DC-DC converter to provide galvanic isolation between the controller and bus sides. The device supports data rates up to 1 Mbps and complies with ISO 11898-2:2016 standards. It features a wide operating supply voltage range for both VDD1 and VDD2 domains. The component includes built-in protection against short circuits and thermal shutdown mechanisms.

Feature Summary

• Integrated isolated DC-DC converter eliminates external transformer requirements
• High electromagnetic immunity and robust fault tolerance
• Compliance with latest ISO 11898-2:2016 automotive standards
• Fail-safe operation under various bus fault conditions

Applications

• Automotive Controller Area Network (CAN) systems
• Industrial automation control networks
• Medical equipment requiring galvanic isolation
• Power electronics communication interfaces

Procurement Notes

Verify the specific suffix 'AB-T-2-G' matches your required tape-and-reel packaging and temperature grade. Confirm that the isolation voltage ratings meet your system safety requirements. Ensure compatibility with your microcontroller logic levels before procurement.

Selection Notes

Select this component when integrated isolation is required without external magnetics. It is suitable for applications demanding high noise immunity and compliance with modern automotive CAN standards. Consider power consumption constraints as the internal DC-DC converter draws current from the primary side.

Part Context

This part belongs to Infineon's ADM3120 family of isolated CAN transceivers. The family offers varying speed grades and package options. The BX variant typically denotes a specific pinout or thermal enhancement. The AB suffix indicates specific electrical characteristics or testing criteria defined by the manufacturer.

Replacement Considerations

Direct replacements include other ADM3120 variants with compatible pinouts. Verify isolation voltage and data rate specifications match. Check if alternative packages require PCB layout adjustments. Ensure substitute parts support the same ISO 11898-2:2016 compliance level.
