TJA1041 High speed CAN transceiver Rev. 06 5 December 2007 Product data sheet 1. General description The TJA1041 provides an advanced interface between the protocol controller and the physical bus in a Controller Area Network (CAN) node. The TJA1041 is primarily intended for automotive high-speed CAN applications (up to 1 Mbit/s). The transceiver provides differential transmit capability to the bus and differential receive capability to the CAN controller. The TJA1041 is fully compatible to the ISO 11898 standard, and offers excellent ElectroMagnetic Compatibility (EMC) performance, very low power consumption, and passive behavior when supply voltage is off. The advanced features include: Low-power management, supporting local and remote wake-up with wake-up source recognition and the capability to control the power supply in the rest of the node Several protection and diagnosis functions including short circuits of the bus lines and rst battery connection Automatic adaptation of the I/O-levels, in line with the supply voltage of the controller 2. Features 2.1 Optimized for in-vehicle high speed communication n Fully compatible with the ISO 11898 standard n Communication speed up to 1 Mbit/s n Very low ElectroMagnetic Emission (EME) n Differential receiver with wide common-mode range, offering high ElectroMagnetic Immunity (EMI) n Passive behavior when supply voltage is off n Automatic I/O-level adaptation to the host controller supply voltage n Recessive bus DC voltage stabilization for further improvement of EME behavior n Listen-only mode for node diagnosis and failure containment n Allows implementation of large networks (more than 110 nodes) 2.2 Low-power management n Very low-current in Standby and Sleep mode, with local and remote wake-up n Capability to power-down the entire node, still allowing local and remote wake-up n Wake-up source recognitionTJA1041 NXP Semiconductors High speed CAN transceiver 2.3 Protection and diagnosis (detection and signalling) n TXD dominant clamping handler with diagnosis n RXD recessive clamping handler with diagnosis n TXD-to-RXD short-circuit handler with diagnosis n Overtemperature protection with diagnosis n Undervoltage detection on pins V , V and V CC I/O BAT n Automotive environment transient protected bus pins and pin V BAT n Short-circuit proof bus pins and pin SPLIT (to battery and to ground) n Bus line short-circuit diagnosis n Bus dominant clamping diagnosis n Cold start diagnosis (rst battery connection) 3.
