TJA1051TK/3/2Z

Drivers, Receivers, Transceivers Overview

The TJA1051TK/3/2Z is a high-speed CAN transceiver designed for automotive applications, providing an interface between a CAN protocol controller and the physical two-wire bus. It supports data rates up to 5 Mbit/s in the CAN FD fast phase and complies with ISO 11898-2:2016 and SAE J2284 standards. The device operates on a VCC supply voltage of 4.5 V to 5.5 V and features a dedicated VIO pin (2.8 V to 5.5 V) enabling direct interfacing with 3 V to 5 V microcontrollers. Packaged in an HVSON8 format (3.0 mm x 3.0 mm), it offers ESD protection of ±8 kV per IEC 61000-4-2, operates within a temperature range of -40 °C to +150 °C, and includes undervoltage detection and thermal shutdown.

Drivers, Receivers, Transceivers Feature Summary

• Supports data rates up to 5 Mbit/s in the CAN FD fast phase
• Features a VIO input for direct connection to 3 V to 5 V microcontrollers
• Provides high electrostatic discharge handling capability on bus pins
• Includes TXD dominant time-out function to prevent permanent bus locking

Drivers, Receivers, Transceivers Applications

• High-speed CAN networks in 12 V and 24 V automotive systems
• Nodes requiring direct interfacing with 3 V or 5 V microcontrollers
• Applications needing low electromagnetic emission and high immunity

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix /2Z against the manufacturer's current documentation to confirm package type and reel specifications. Ensure that the HVSON8 footprint matches the design requirements for the exposed center pad soldering. Confirm RoHS compliance status directly from the datasheet before finalizing procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this variant specifically when a VIO pin is required to adapt logic levels for 3 V to 5 V microcontrollers. The HVSON8 package is suitable for designs prioritizing small board area and improved automated optical inspection capabilities. This part is intended for nodes that do not require standby mode wake-up via the bus.

Drivers, Receivers, Transceivers Part Context

The TJA1051 series represents the third generation of NXP high-speed CAN transceivers, succeeding devices like the TJA1050. It improves upon previous generations by offering enhanced EMC performance and higher ESD tolerance. The TK/3 designation indicates the HVSON8 package version equipped with the VIO pin for flexible microcontroller integration.
