TCAN1145DRQ1 Automotive CAN FD Transceiver by Texas Instruments

The TCAN1145DRQ1 from Texas Instruments is a high-performance, automotive-grade Controller Area Network Flexible Data-Rate (CAN FD) transceiver that serves as an interface between a CAN protocol controller and the physical two-wire CAN bus. Designed to operate in harsh automotive environments, this transceiver is capable of withstanding the challenges of the automotive industry, including those related to electromagnetic compatibility (EMC).

With a broad operating temperature range of -40°C to +125°C, the TCAN1145DRQ1 is suitable for a variety of automotive applications, from powertrain and chassis control to in-vehicle networking and body electronics. It supports CAN FD data rates up to 5 Mbps, allowing for faster data transmission and more efficient communication between electronic control units (ECUs) within a vehicle.

The device is housed in a compact 8-pin SOIC package, making it a space-saving solution for modern automotive designs. It features robust protection against transients and faults, including thermal shutdown, overvoltage, and loss of ground and supply protections, ensuring reliable operation under adverse conditions. Furthermore, the TCAN1145DRQ1 has a low-power mode with a remote wake-up capability to minimize the power consumption when the vehicle is in a dormant state.

Key features of the TCAN1145DRQ1 include:

• Compliance with the ISO 11898-2:2016 standard and ISO 11898-5:2007
• Support for both CAN and CAN FD protocols
• Differential receiver with wide common-mode range for improved noise immunity
• Transmit data (TXD) dominant time-out function to prevent bus lock-up
• Under-voltage detection on VCC and VIO pins
• Bus fault protection of ±58V on CANH and CANL pins
• Electrostatic discharge (ESD) protection of ±16kV HBM on bus pins

Designed with the needs of the modern automobile in mind, the TCAN1145DRQ1 ensures robust communication and contributes to the safety and reliability of the vehicle's network systems. Its integration into automotive designs helps engineers meet the stringent requirements for data transmission and error handling in advanced vehicle architectures.
