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 (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 is a up from the TJA1050 high-speed CAN transceiver. 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

产品特点 Features

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)
VIO 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 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)

2.3 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 VCC and VIO
Thermally protected
