The NXP TJA1057T is a high-speed CAN transceiver that serves as an interface between a Controller Area Network (CAN) protocol controller and the physical two-wire CAN bus. Designed to provide differential transmit and receive capability to (micro)controllers with a CAN protocol controller, the TJA1057T is an essential component in automotive and industrial applications where reliable data communication is crucial.
Key Features
- ISO 11898-2:2016 Compliant: The device adheres to the latest CAN standard, ensuring interoperability and reliable performance in systems using the high-speed CAN physical layer.
- Low Power Mode: With a very low current standby mode, the TJA1057T is ideal for power-sensitive applications, helping to reduce overall energy consumption.
- Transmit Data (TXD) Dominant Time-out Function: This feature prevents bus lines from being driven to a permanent dominant state, thus enhancing error management and system recovery.
- Bus Pins Protected Against Transients: The device is designed to withstand the harsh electrical environments typical in automotive applications, offering protection against transients in the automotive environment.
- Silent Mode: In silent mode, the TJA1057T disables its transmitter while still capable of receiving data, allowing it to be used in nodes where transmit functionality is not required.
