CANbus Protocol High Speed Transceiver TJA1050T/CM TJA1050 Thermally Protected

TJA1050T/CM TJA1050 High speed Transceiver with Thermally protected

GENERAL DESCRIPTION                                                                

The TJA1050 is the interface between the CAN protocol

controller and the physical bus. The device provides

differential transmit capability to the bus and differential

receive capability to the CAN controller.

The TJA1050 is the successor to the PCA82C250 high

speed CAN transceiver. The most important

improvements are:

• Much lower ElectroMagnetic Emission (EME) due to

optimal matching of the CANH and CANL output signals

• Improved behaviour in case of an unpowered node

FEATURES

• Fully compatible with the “ISO 11898” standard

• High speed (up to 1 Mbaud)

• Transmit Data (TXD) dominant time-out function

• Bus lines protected against transients in an automotive

environment

• Silent mode in which the transmitter is disabled

• Differential receiver with wide common-mode range for

high ElectroMagnetic Immunity (EMI)

• Input levels compatible with 3.3 V devices

• Thermally protected

• Short-circuit proof to battery and ground

• An unpowered node does not disturb the bus lines

• At least 110 nodes can be connected.
