TJR1441 High-speed CAN transceiver Rev. 2 15 October 2021 Product data sheet 1 General description The TJR1441 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 TJR1441 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 TJR1441 to be easily retrofitted to existing applications. An AEC-Q100 Grade 1 variant, the TJA1441, is available to support operation at 125 C ambient temperature. A variant intended for industrial applications, the TJF1441, is also available. 1.1 TJR1441 variants The TJR1441 comes in three variants, each available in an SO8 or HVSON8 package: The TJR1441A 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 TJR1441B is a high-speed CAN transceiver with Normal and Silent modes. The TJR1441D 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 0 Silent mode for node diagnosis and failure containment TJR1441A only: VIO input for interfacing with 3.3 V to 5 V microcontrollers TJR1441D only: dedicated input for switching to very low-current Off mode and disengaging from the busNXP Semiconductors TJR1441 High-speed CAN transceiver 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. 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 supply voltage drops below the Off mode threshold Internal biasing of TXD and mode selection input pins, to enable defined fail-safe behavior 2.3 Protection High ESD handling capability on the bus pins (8 kV IEC and HBM) Bus pins protected against transients in automotive environments Transmit Data (TXD) dominant time-out function Thermally protected TJR1441 All information provided in this document is subject to legal disclaimers.
