TJA1051

High-speed CAN transceiver

Rev. 6 — 25 March 2011

Product data sheet

1. General description

The TJA1051 is a high-speed CAN transceiver that provides an interface between a

Controller Area Network (CAN) protocol controller and the physical two-wire CAN bus.

The transceiver is designed for high-speed (up to 1 Mbit/s) CAN applications in the

automotive industry, providing differential transmit and receive capability to (a

microcontroller with) a CAN protocol controller.

The TJA1051 belongs to the third generation of high-speed CAN transceivers from NXP

Semiconductors, offering significant improvements over first- and second-generation

devices such as the TJA1050. It offers improved ElectroMagnetic Compatibility (EMC)

and ElectroStatic Discharge (ESD) performance, and also features:

• Ideal passive behavior to the CAN bus when the supply voltage is off

• TJA1051T/3 and TJA1051TK/3 can be interfaced directly to microcontrollers with

supply voltages from 3 V to 5 V

These features make the TJA1051 an excellent choice for all types of HS-CAN networks,

in nodes that do not require a standby mode with wake-up capability via the bus.

2. Features and benefits

2.1 General

Fully ISO 11898-2 compliant

Suitable for 12 V and 24 V systems

Low ElectroMagnetic Emission (EME) and high ElectroMagnetic Immunity (EMI)

V_IOinput on TJA1051T/3 and TJA1051TK/3 allows for direct interfacing with 3 V to 5 V

microcontrollers (available in SO8 and very small HVSON8 packages respectively)

EN input on TJA1051T/E allows the microcontroller to switch the transceiver to a very

low-current Off mode

Available in SO8 and HVSON8 packages

Leadless HVSON8 package (3.0 mm × 3.0 mm) with improved Automated Optical

Inspection (AOI) capability

Dark green product (halogen free and Restriction of Hazardous Substances (RoHS)

compliant)

2.2 Low-power management

Functional behavior predictable under all supply conditions

Transceiver disengages from the bus when not powered up (zero load)
