TJA1044V High-speed CAN transceiver with Standby mode Rev. 1 2 March 2018 Product data sheet 1. General description The TJA1044V is part of the Mantis family of high-speed CAN transceivers. It provides an interface between a Controller Area Network (CAN) protocol controller and the physical two-wire CAN bus. The transceiver is designed for high-speed CAN applications in the automotive industry, providing the differential transmit and receive capability to (a microcontroller with) a CAN protocol controller. The TJA1044V offers a feature set optimized for 12 V automotive applications, with significant improvements over NXP s first- and second-generation CAN transceivers, such as the TJA1040 and TJA1042, and excellent ElectroMagnetic Compatibility (EMC) performance. Additionally, the TJA1044V features: Ideal passive behavior to the CAN bus when the supply voltage is off A very low-current Standby mode with bus wake-up capability Excellent EMC performance at speeds up to 500 kbit/s, even without a common mode choke TJA1044VT/3 and TJA1044VTK/3 can be interfaced directly to microcontrollers with supply voltages from 3Vto5V These features make the TJA1044V an excellent choice for all types of HS-CAN networks, in nodes that require a low-power mode with wake-up capability via the CAN bus. The TJA1044V implements the CAN physical layer as defined in ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5. This implementation enables reliable communication in the CAN FD fast phase at data rates up to 5 Mbit/s. 2. Features and benefits 2.1 General Fully ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5 compliant Certified according to latest VeLIO (Vehicle LAN Interoperability and Optimization) test requirements Very low-current Standby mode with host and bus wake-up capability Optimized for use in 12 V automotive systems EMC performance satisfies Hardware Requirements for LIN, CAN and FlexRay Interfaces in Automotive Applications, Version 1.3, May 2012. AEC-Q100 qualified Dark green product (halogen free and Restriction of Hazardous Substances (RoHS) compliant)TJA1044V NXP Semiconductors High-speed CAN transceiver with Standby mode V input on TJA1044Vx/3 variants allows for direct interfacing with 3 V to 5 V IO microcontrollers. Variants without a V pin can interface with 3.3 V and 5 V-supplied IO microcontrollers, provided the microcontroller I/Os are 5 V tolerant. Both V and non-V variants are available in SO8 and leadless HVSON8 (3.0 IO IO mm 3.0 mm) packages HVSON8 with improved Automated Optical Inspection (AOI) capability. 2.2 Predictable and fail-safe behavior Functional behavior predictable under all supply conditions Transceiver disengages from bus when not powered (zero load) Transmit Data (TXD) and bus dominant time-out functions Internal biasing of TXD and STB input pins 2.3 Protection High ESD handling capability on the bus pins (8 kV IEC and HBM) Bus pins protected against transients in automotive environments Undervoltage detection on pins V and V CC IO Thermally protected 2.4 TJA1044V CAN FD Timing guaranteed for CAN FD data rates up to 5 Mbit/s Improved TXD to RXD propagation delay of 210 ns TJA1044V All information provided in this document is subject to legal disclaimers.
