NXP PCA82C251T CAN Transceiver
The PCA82C251T is a high-speed CAN (Controller Area Network) transceiver designed by NXP Semiconductors. This transceiver serves as an interface between a CAN protocol controller and the physical two-wire CAN bus. It is designed to provide differential transmit and receive capability to (CANH and CANL) and is fully compatible with the ISO 11898-2 standard.
Featuring robustness and high electromagnetic immunity, the PCA82C251T is well-suited for automotive applications and other demanding industrial environments. Its primary function is to ensure that the CAN signaling on the bus is translated to levels that the CAN controller can interpret, while also protecting the CAN controller from transients and other electrical disturbances present on the bus.
Key Features
- ISO 11898-2 Compliant: The device adheres to the high-speed CAN specification, ensuring reliable communication up to 1 Mbps.
- Differential Bus Outputs: The transceiver's outputs are designed to handle high differential voltage, which makes the communication robust against disturbances.
- Thermal Protection: The PCA82C251T includes an integrated thermal protection circuit that disables the transmitter in case of excessive temperature.
