TJR1443 High-speed CAN transceiver with Sleep mode Rev. 2 15 October 2021 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 behaviorNXP Semiconductors TJR1443 High-speed CAN transceiver with Sleep mode 2.3 Low-power management Very low-current Standby and Sleep modes, with host, local and bus wake-up capability Entire node with TJR1443 can be powered down while still supporting local, bus and host wake-up CAN wake-up receiver powered by V allowing V and V to be shut down BAT IO CC CAN wake-up pattern filter time of 0.5 s to 1.8 s, meeting Classical CAN and CAN FD requirements 2.4 Diagnosis & Protection Overtemperature diagnosis Transmit Data (TXD) dominant time-out and TXD-to-RXD short-circuit handler with diagnosis Bus dominant clamping diagnosis Cold start diagnosis (first battery connection) High ESD handling capability on the bus pins (8 kV IEC and HBM) Bus pins and VBAT protected against transients in automotive environments Thermally protected TJR1443 All information provided in this document is subject to legal disclaimers.
