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.

FEATURES
Optimized for in-vehicle high speed communication
• Fully compatible with the ISO 11898 standard
• Communication speed up to 1 Mbit/s
• Very low ElectroMagnetic Emission (EME)
• Differential receiver with wide common-mode range, offering high ElectroMagnetic Immunity (EMI)
• Passive behaviour when supply voltage is off
• Automatic I/O-level adaptation to the host controller supply voltage
• Recessive bus DC voltage stabilization for further improvement of EME behaviour
• Listen-only mode for node diagnosis and failure containment
• Allows implementation of large networks (more than 110 nodes).

Low-power management
• Very low-current in standby and sleep mode, with local and remote wake-up
• Capability to power down the entire node, still allowing local and remote wake-up
• Wake-up source recognition.

Protection and diagnosis (detection and signalling)
• TXD dominant clamping handler with diagnosis
• RXD recessive clamping handler with diagnosis
• TXD-to-RXD short-circuit handler with diagnosis
• Over-temperature protection with diagnosis
• Undervoltage detection on pins VCC, VI/O and VBAT
• Automotive environment transient protected bus pins and pin VBAT
• Short-circuit proof bus pins and pin SPLIT (to battery and to ground)
• Bus line short-circuit diagnosis
• Bus dominant clamping diagnosis
• Cold start diagnosis (first battery connection).
