工作原理
The CAN Transceiver Interface operates by receiving digital data from the CAN controller, converting it into differential voltage signals (CAN_H and CAN_L) for transmission on the bus. During reception, it detects differential voltage levels on the bus, converts them back to digital signals, and provides them to the CAN controller. It includes features like bus fault protection, thermal shutdown, and common-mode rejection to maintain communication integrity.
