Working Principles

The SN65HVD23P is a transceiver designed for Controller Area Network (CAN) bus communication. It enables reliable data transmission between nodes in automotive and industrial applications. The transceiver uses differential signaling to provide noise immunity and robustness in harsh environments.

The device operates by converting the digital signals from the controller into differential voltage levels on the CANH and CANL lines. It also receives differential signals from the bus and converts them into digital signals for the controller. The transceiver incorporates fail-safe features to handle bus fault conditions and provides thermal shutdown and short-circuit protection.
