TJA1054AT/VM,518

Drivers, Receivers, Transceivers Overview

The NXP TJA1054AT/VM,518 is a fault-tolerant CAN transceiver designed for low-speed automotive applications up to 125 kBd. It operates within a VCC supply voltage range of 4.75V to 5.25V and supports a battery supply voltage (VBAT) from 5.0V to 27V. The device features a virtual junction temperature rating of -40°C to +150°C. It provides differential receive and transmit capabilities but automatically switches to single-wire mode during bus failures, including short-circuits to VCC. The component includes integrated receiver filters, slope control for low electromagnetic emission, and protection against short circuits to battery and ground.

Drivers, Receivers, Transceivers Feature Summary

• Automatic switching to single-wire transmission mode upon detection of specific bus wiring faults
• Integrated slope control function to minimize electromagnetic emissions on unshielded bus lines
• Low power consumption in sleep and standby modes with wake-up capability via bus lines or local input

Drivers, Receivers, Transceivers Applications

• Low-speed Controller Area Network (CAN) communication in passenger cars
• Automotive electronic systems requiring fault-tolerant physical layer interfaces
• Industrial motor drives and Programmable Logic Controllers (PLCs) utilizing CANbus protocols

Drivers, Receivers, Transceivers Procurement Notes

Verify the complete ordering suffix 'VM,518' against official NXP documentation to confirm package type and reel specifications. Ensure compatibility with existing PCB footprints for SO14 packages. Confirm RoHS compliance status for the specific manufacturing batch prior to integration into production assemblies.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring robust fault tolerance in automotive environments where bus line integrity may be compromised. It serves as an ESD-improved replacement for legacy devices like the PCA82C252T and TJA1053T. Consider its low-power modes for battery-operated systems requiring efficient wake-up mechanisms.

Drivers, Receivers, Transceivers Part Context

The TJA1054A represents an enhanced version of the TJA1054, offering improved ElectroStatic Discharge (ESD) performance. It maintains pin and downward compatibility with earlier generations while providing better electromagnetic compatibility. This series is widely used in automotive networks to ensure reliable communication under adverse electrical conditions.

Drivers, Receivers, Transceivers Replacement Considerations

The TJA1054AT is pin-compatible with the PCA82C252T and TJA1053T, allowing direct substitution in existing designs without circuit modifications.
