General description
The TJA1041A provides an advanced interface between the protocol controller and the physical bus in a Controller Area Network (CAN) node. The TJA1041A 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 behavior 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 behavior
■ 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
■ Overtemperature 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)
