TJA1441

High-speed CAN transceiver

Rev. 1 — 12 August 2020

Product data sheet

1 General description

The TJA1441 is a member of the TJA144x family of transceivers that provide an interface

between a Controller Area Network (CAN) or CAN FD (Flexible Data rate) protocol

controller and the physical two-wire CAN bus. TJA144x transceivers implement the CAN

physical layer as defined in ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5, and

are fully interoperable with high-speed Classical CAN and CAN FD transceivers. All

TJA144x variants enable reliable communication in the CAN FD fast phase at data rates

up to 5 Mbit/s.

The TJA1441 is intended as a simple replacement for high-speed Classical CAN

and CAN FD transceivers, such as the TJA1051 or TJA1057 from NXP. It offers pin

compatibility and is designed to avoid changes to hardware and software design,

allowing the TJA1441 to be easily retrofitted to existing applications.

An AEC-Q100 Grade 0 variant, the TJR1441, is available for high temperature

applications, supporting operation at 150 °C ambient temperature. A variant intended for

industrial applications, the TJF1441, is also available.

1.1 TJA1441 variants

The TJA1441 comes in three variants, each available in an SO8 or HVSON8 package:

• The TJA1441A is a high-speed CAN transceiver with Normal and Silent modes and a

VIO supply pin. The VIO pin allows for direct interfacing with 3.3 V and 5 V-supplied

microcontrollers.

• The TJA1441B is a high-speed CAN transceiver with Normal and Silent modes.

• The TJA1441D is a high-speed CAN transceiver with Normal and Silent modes with a

transmitter/receiver On/Off input.

2 Features and benefits

2.1 General

• ISO 11898-2:2016, SAE J2284-1 to SAE J2284-5 and SAE J1939-14 compliant

• Standard CAN and CAN FD data bit rates up to 5 Mbit/s

• Low Electromagnetic Emission (EME) and high Electromagnetic Immunity (EMI)

• Qualified according to AEC-Q100 Grade 1

• Silent mode for node diagnosis and failure containment

• TJA1441A only: VIO input for interfacing with 3.3 V to 5 V microcontrollers

• TJA1441D only: dedicated input for switching to very low-current Off mode and

disengaging from the bus

• All variants are available in SO8 and leadless HVSON8 (3.0 mm x 3.0 mm) packages;

HVSON8 with improved Automated Optical Inspection (AOI) capability.
