Working Principles

The TCAN1051HGDRBTQ1 is a transceiver designed for Controller Area Network (CAN) bus communication. It operates based on the CAN 2.0B protocol, which is widely used in automotive applications for reliable and efficient data exchange between electronic control units (ECUs).

The transceiver receives digital signals from the microcontroller through the RXD pin and converts them into differential voltage levels on the CANH and CANL pins. These voltage levels represent the logical states of the transmitted data.

During transmission, the transceiver converts the differential voltage levels received on the TXD pin into digital signals suitable for the microcontroller. It also provides protection against EMI by suppressing noise and ensuring signal integrity.

The RS pin controls the standby mode of the transceiver, allowing it to enter a low-power state when not actively transmitting or receiving data. The wake-up capability enables the transceiver to resume normal operation upon receiving specific wake-up patterns on the CAN bus.

Detailed Application Field Plans

The TCAN1051HGDRBTQ1 is primarily used in automotive applications where reliable and high-speed communication is required. Some specific application fields include:

1. Automotive body control modules
2. Engine control units
3. Transmission control units
4. Infotainment systems
5. Advanced driver-assistance systems (ADAS)
6. Electric vehicle powertrain control
