Typical Applications
TCAN1473A-Q1 is suitable for 6 applications: Body Electronics and Lighting, Automotive Gateway, ADAS, Infotainment and Cluster, Hybrid, Electric, and Powertrain Systems, Electric Bikes and Industrial Transportation.
Body Electronics and Lighting
The TCAN1473A-Q1 is ideal for body electronics and lighting systems in vehicles. Its SIC functionality actively shapes CAN bus signals, reducing ringing and electromagnetic emissions, which is critical for reliable communication across the body network with many nodes. The sleep mode and INH/WAKE pins enable low-power operation during ignition-off states, extending battery life. With data rates up to 8 Mbps, it supports advanced lighting control and body functions. AEC-Q100 qualification ensures robustness in automotive environments.
Recommended
Automotive Gateway
Automotive gateways aggregate multiple CAN FD subnetworks, requiring a transceiver that handles high data rates without signal degradation. The TCAN1473A-Q1's SIC capability allows it to maintain signal integrity over long bus lengths and with multiple unterminated stubs, which is typical in gateway designs. Its INH output can drive external power switches to manage power domains. The device supports both classical CAN and CAN FD up to 8 Mbps, providing flexibility for legacy and modern protocols.
Recommended
ADAS
In Advanced Driver Assistance Systems (ADAS), sensors and controllers exchange high-bandwidth data with strict timing requirements. The TCAN1473A-Q1 meets ISO 11898-2:2024 and supports CAN FD up to 8 Mbps, providing the speed needed for real-time sensor fusion. Its SIC feature reduces signal ringing that can cause communication errors in complex topologies with stub branches. The sleep mode helps reduce power consumption when the vehicle is parked, and the WAKE pin allows system wake-up on network activity.
Recommended
Infotainment and Cluster
Infotainment and instrument clusters require reliable, high-speed communication between the head unit, display, and vehicle systems. The TCAN1473A-Q1's SIC enables clean signal transmission at 2 Mbps and above, preventing glitches in audio or display data. Its low quiescent current in sleep mode supports always-on systems without draining the vehicle battery. The 14-VSON package is compact for space-constrained dashboard electronics, and AEC-Q100 qualification ensures reliability under extreme temperatures.
Recommended
Hybrid, Electric, and Powertrain Systems
Hybrid and electric powertrain systems involve multiple electronic control units (ECUs) managing battery, motor, and charging functions. The TCAN1473A-Q1 is designed for these high-noise environments, with SIC reducing emissions and bus fault protection guarding against short circuits and transients. It supports CAN FD up to 8 Mbps to handle large data packets from battery management systems. The sleep mode helps reduce draw when the vehicle is off, while the INH pin can control power to downstream components.
Recommended
Electric Bikes and Industrial Transportation
For electric bikes and industrial transportation, the TCAN1473A-Q1 provides robust CAN communication in compact, battery-powered designs. Its low-power sleep mode is essential for energy conservation, and the SIC feature ensures reliable data transfer even with long bus cables and many nodes. The device is AEC-Q100 qualified, making it suitable for the vibration and temperature extremes found in industrial settings. It supports both classical CAN and CAN FD, enabling protocol migration without hardware changes.

Key Differentiators
- SIC functionality for reduced ringing (vs TCAN1043N-Q1)
- Automotive AEC-Q100 qualification (vs SN65HVD230DR)
- Sleep mode with INH and WAKE pins (vs TCAN1042DRQ1)
Design Notes
Proper bus termination is critical for CAN FD networks. Place the 120-ohm termination resistor at both ends of the bus to match the characteristic impedance. The SIC feature reduces ringing, but the termination must be kept close to the transceiver pins to minimize stub length. Ensure the CANH and CANL traces are routed as a balanced differential pair with controlled impedance to reduce emissions.
The TCAN1473A-Q1 is designed for automotive environments with ambient temperatures up to 125C. Ensure adequate copper pour on the PCB around the device to dissipate heat from the power dissipation of the transceiver. The 14-VSON package has a thermal pad that should be connected to the ground plane with multiple vias to improve thermal performance.
Do not exceed the maximum bus voltage or connect the transceiver directly to a high-voltage bus without protection. The device includes bus fault protection up to Β±58V, but external transient protection diodes are recommended for severe voltage spikes. Also, ensure the WAKE and INH pins are properly handled to avoid unintended wake-up events, which can drain the battery.
