TJA1041A

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 controllersupply voltage

· Bus line short-circuit diagnosis
· Bus dominant clamping diagnosis
· Cold start diagnosis (first battery connection).

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. The TJA1041A is fully compatible to the ISO 11898 standard, and offers excellent EMC  performance, very low power consumption, and passive behaviour 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 first battery connection · Automatic adaptation of the I/O-levels, in line with the supply voltage of the controller.
