TJA1051TK/3 High-Speed CAN Transceiver (3.3V Logic, HVSON8)

Build ultra-reliable, noise-immune communication networks for your custom drones and robotics with the TJA1051TK/3 high-speed CAN transceiver. As protocols like DroneCAN and UAVCAN become the gold standard for connecting Flight Controllers to ESCs, GPS modules, and smart sensors, having a robust physical layer is absolutely critical. This IC serves as the perfect bridge between your microcontroller's CAN controller and the physical two-wire CAN bus.

What makes the "/3" variant of the TJA1051 so valuable is its dedicated VIO pin. This allows the transceiver to interface directly with 3.3V logic microcontrollers (like the STM32 used on almost all modern flight controllers) without the need for additional voltage level shifters, while still driving the CAN bus with a solid 5V. Fully supporting CAN FD (Flexible Data-rate) at speeds up to 5 Mbps, and housed in an ultra-compact, thermally efficient HVSON8 leadless package, it is the ultimate choice for lightweight, professional-grade RC electronics.

Key Features:

• DroneCAN / UAVCAN Ready: The perfect physical layer interface for robust, long-distance communication in high-EMI environments (like drone frames with powerful brushless motors).

• 3.3V Logic Compatible: Features a dedicated VIO pin, allowing direct connection to 3.3V microcontrollers (STM32, ESP32) without level shifting.

• High-Speed Data: Fully supports modern CAN FD networks with data rates up to 5 Mbps.

• Ultra-Compact Footprint: The 3x3 mm HVSON8 package saves critical PCB space on densely populated flight controllers and tiny sensor nodes.
