Working Principles

The TJA1028T/3V3/10/2Z is a CAN transceiver that facilitates communication between microcontrollers or other electronic control units in automotive systems. It operates based on the Controller Area Network (CAN) protocol, which is widely used in vehicles for reliable data exchange.

The transceiver receives digital signals from the microcontroller's TXD pin and converts them into differential voltage signals on the CANH and CANL pins. These signals are then transmitted over a twisted-pair bus to other nodes in the network. Similarly, it receives differential voltage signals from the bus and converts them back into digital signals for the microcontroller to process.

The transceiver also incorporates protection features such as overvoltage, undervoltage, and short-circuit protection to safeguard against potential electrical faults and ensure the integrity of the communication system.
