TJA1043 High-speed CAN transceiver Rev. 3 24 April 2013 Product data sheet 1. General description The TJA1043 is a high-speed CAN transceiver that 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 (up to 1 Mbit/s) CAN applications in the automotive industry, providing differential transmit and receive capability to (a microcontroller with) a CAN protocol controller. The TJA1043 belongs to the third generation of high-speed CAN transceivers from NXP Semiconductors, offering significant improvements over first- and second-generation devices such as the TJA1041A. It offers improved ElectroMagnetic Compatibility (EMC) and ElectroMagnetic Discharge (ESD) performance, very low power consumption, and passive behavior when the supply voltage is turned off. Advanced features include: Low-power management controls the power supply throughout the node while supporting local and remote wake-up with wake-up source recognition Several protection and diagnostic functions including bus line short-circuit detection and battery connection detection Can be interfaced directly to microcontrollers with supply voltages from 3 V to 5 V These features make the TJA1043 the ideal choice for high speed CAN networks containing nodes that need to be available all times, even when the internal V and V IO CC supplies are switched off. 2. Features and benefits 2.1 General Fully ISO 11898-2 and ISO 11898-5 compliant Suitable for 12 V and 24 V systems Low ElectroMagnetic Emission (EME) and high ElectroMagnetic Immunity (EMI) V input allows for direct interfacing with 3 V and 5 V microcontrollers IO SPLIT voltage output for stabilizing the recessive bus level Listen-only mode for node diagnosis and failure containment Available in SO14 and HVSON14 packages Leadless HVSON14 package (3.0 mm 4.5 mm) with improved Automated Optical Inspection (AOI) capability Dark green product (halogen free and Restriction of Hazardous Substances (RoHS) compliant)TJA1043 NXP Semiconductors High-speed CAN transceiver 2.2 Low-power management Very low current Standby and Sleep modes, with local and remote wake-up Capability to power down the entire node while supporting local, remote and host wake-up Wake-up source recognition Transceiver disengages from the bus (zero load) when V absent BAT Functional behavior predictable under all supply conditions 2.3 Protection and diagnosis (detection and signalling) High ESD handling capability on the bus pins Bus pins and V protected against transients in automotive environments BAT Transmit Data (TXD) dominant time-out function with diagnosis TXD-to-RXD short-circuit handler with diagnosis Thermal protection with diagnosis Undervoltage detection and recovery on pins V , V and V CC IO BAT Bus line short-circuit diagnosis Bus dominant clamping diagnosis Cold start diagnosis (first battery connection) 3.
