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)
