• Includes watchdog timer functionality for enhanced system reliability
• Complies with ISO 11898-2:2016 standards for automotive applications

Drivers, Receivers, Transceivers Applications

• Automotive body control modules requiring CAN FD connectivity
• Gateway nodes in vehicle networks utilizing selective wake capabilities
• Electronic control units (ECUs) needing robust bus diagnostics
• Local networking systems optimizing power consumption through sleep modes

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix DRQ1 corresponds to the SOIC-14 package and reel packaging configuration. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Ensure the ordering part number matches the exact functional requirements, as suffixes may indicate variations in tape and reel quantities or temperature grades. Cross-reference the manufacturer's latest datasheet for any updates on recommended soldering profiles.

Drivers, Receivers, Transceivers Selection Notes

Select this component when SPI configurability and integrated watchdog timers are required for automotive CAN FD networks. It serves as a suitable alternative to basic transceivers by offering advanced diagnostic features. Consider the SOIC-14 footprint for PCB layout compatibility. Evaluate the 120 mA supply current against system power budgets. Ensure the 4.5 V minimum supply voltage aligns with the target application's power rail availability.

Drivers, Receivers, Transceivers Part Context

The TCAN1145DRQ1 belongs to the TCAN114x-Q1 family of enhanced high-speed CAN FD transceivers. This series provides register-compatible flexibility, allowing designers to implement various network topologies without hardware changes. Unlike simpler transceivers, it integrates configurable features such as selective wake and bus fault detection, making it ideal for complex automotive architectures requiring efficient node management.

Drivers, Receivers, Transceivers Replacement Considerations

The TCAN1145DMTRQ1 offers identical functionality but utilizes a VSON-14 package instead of SOIC-14. Designers must verify PCB footprint compatibility before substitution. Other members of the TCAN114x-Q1 family, such as the TCAN1146, provide additional features like LIMP mode but may require software adjustments due to pinout or register differences.
