High-speed CAN transceiver with Sleep mode

Rev. 1 — 7 September 2020

Product data sheet

1 General description

The TJR1443 is a member of the TJR144x 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. TJR144x 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 TJR144x variants enable reliable communication in the CAN FD fast

phase at data rates up to 5 Mbit/s and are qualified to AEC-Q100 Grade 0, supporting

operation at 150 °C ambient temperature.

The TJR1443 is intended as a simple replacement for high-speed Classical CAN and

CAN FD transceivers, such as the TJA1043 from NXP. It offers pin compatibility and is

designed to avoid changes to hardware and software design, allowing the TJR1443 to be

easily retrofitted to existing applications.

An AEC-Q100 Grade 1 variant, the TJA1443, is available to support operation at 125 °C

ambient temperature.

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 0

• VIO input for interfacing with 3.3 V to 5 V microcontrollers

• Listen-only mode for node diagnosis and failure containment

• Available in SO14 and leadless HVSON14 (3.0 mm x 4.5 mm) packages; HVSON14

with improved Automated Optical Inspection (AOI) capability.

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

compliant)

2.2 Predictable and fail-safe behavior

• Undervoltage detection with defined handling on all supply pins

• Full functionality guaranteed from the undervoltage detection thresholds up to the

maximum limiting voltage values

• Defined behavior below the undervoltage detection thresholds

• Transceiver disengages from the bus (high-ohmic) when the battery voltage drops

below the Off mode threshold

• Internal biasing of TXD and mode selection input pins, to enable defined fail-safe

behavior
