TJA1051 High-Speed CAN Transceiver

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 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

Features

General Features

Fully ISO 11898-2:2003 compliant
Timing guaranteed for data rates up to 5 Mbit/s in the CAN FD fast phase
Suitable for 12 V and 24 V systems
Low ElectroMagnetic Emission (EME) and high ElectroMagnetic Immunity (EMI)
V_IO input 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 package or 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)
AEC-Q100 qualified

Low-power Management

Functional behavior predictable under all supply conditions
Transceiver disengages from the bus when not powered up (zero load)

Protection

High ElectroStatic Discharge (ESD) handling capability on the bus pins
Bus pins protected against transients in automotive environments
Transmit Data (TXD) dominant time-out function
Undervoltage detection on pins V_CC and V_IO
Thermally protected
