TJF1441 High-speed CAN transceiver Rev. 2 15 October 2021 Product data sheet 1 General description The TJF1441 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 TJF1441 is designed for CAN industrial applications allowing networks to run at very low bit rates up to 5 Mbit/s CAN-FD. A VIO supply input allows for direct interfacing with 3.3 V and 5 V-supplied microcontrollers. It is intended as a replacement for high- speed Classical CAN and CAN FD transceivers, such as the TJF1051 from NXP. It offers pin compatibility and is designed to avoid changes to hardware and software design, allowing the TJF1441 to be easily retrofitted to existing applications. A variant intended for high-speed CAN applications in the automotive industry, the TJA1441, is also available. 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 Optimized for industrial applications Low Electromagnetic Emission (EME) and high Electromagnetic Immunity (EMI) Silent mode for node diagnosis and failure containment VIO input for interfacing with 3.3 V to 5 V microcontrollers Available in SO8 package 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 pin, to enable defined fail-safe behaviorNXP Semiconductors TJF1441 High-speed CAN transceiver 2.3 Protection High ESD handling capability on the bus pins (8 kV IEC and HBM) Thermally protected 3 Quick reference data Table 1.Quick reference data Symbol Parameter Conditions Min Typ Max Unit V supply voltage 4.5 - 5.5 V CC I supply current Normal mode, dominant - 38 60 mA CC Normal mode, recessive - 4 7 mA Silent mode - 3 6 mA V undervoltage detection voltage 4 - 4.5 V uvd(VCC) on pin VCC V undervoltage hysteresis voltage 50 - - mV uvhys(VCC) on pin VCC V supply voltage on pin VIO 2.95 - 5.5 V IO I supply current on pin VIO Normal mode, dominant V = 0 V - 250 760 A IO TXD Normal mode, recessive V = V - 150 460 A TXD IO Silent mode V = V - 70 200 A TXD IO V switch-off undervoltage detection 2.65 - 2.95 V uvd(swoff)(VIO) voltage on pin VIO V electrostatic discharge voltage IEC 61000-4-2 on pins CANH and CANL -8 - +8 kV ESD V voltage on pin CANH limiting value according to IEC 60134 -36 - +40 V CANH V voltage on pin CANL limiting value according to IEC 60134 -36 - +40 V CANL T virtual junction temperature -40 - +150 C vj 4 Ordering information Table 2.Ordering information Type number Package Name Description Version TJF1441AT SO8 plastic small outline package 8 leads body width 3.9 mm SOT96-1 TJF1441 All information provided in this document is subject to legal disclaimers.
