(021)TJA1050 CAN Controller Interface Module Bus Drive Interface Module

The TJA1050 is the interface between the Controller Area Network (CAN) protocol controller and the physical bus. The TJA1050 provides different transmit performance for the bus and provides different receive performance for the CAN controller. The TJA1050 is the successor to the PCA82C250 high-speed CAN transceiver. The TJA1050 has made significant improvements in the following areas： CANH and CANL ideally match to minimize electromagnetic emissions. Performance is improved when there is no power-on node. Features： 1. Fully compatible with the "ISO 11898" standard. 2. High speed (up to 1M baud). 3. Low electromagnetic radiation (EME). 4. Differential receiver with wide input range for immunity to electromagnetic interference (EMI). 5. Nodes that are not powered up will not interfere with the bus. 6. Send data (TXD) control timeout function. 7. Silent mode when sending disable. 8. Automatically protect bus pins during transients. 9. Input stage compatible with 3.3V devices. 10. Thermal Protection. 11. Short circuit protection for power and ground. 12. Can connect at least 110 nodes.
