It handles the protocol and data-link layer for CAN 2.0 and CAN FD frames, offloading the host MCU from bit-timing and message-filtering tasks. Rated for the automotive temperature range and AEC-Q100 qualified, this part is suited for under-hood and chassis-domain ECUs, as well as industrial automation nodes that require the higher data throughput of CAN FD (up to 8 Mbps payload vs 1 Mbps for classic CAN). ## Package and mounting — wettable-flank QFN The 20-VFQFN package with exposed thermal pad (3.5x4.5 mm body) uses a wettable-flank terminal finish. This allows the side of each pad to wick solder, enabling automated optical inspection (AOI) of the solder joint — a requirement for automotive-grade assembly where hidden QFN heel fillets are not visible. Surface-mount assembly with the wettable flank means the same footprint and stencil aperture as a standard QFN, but the side-wetting lands give the quality team a visual pass/fail criterion on the reflow line. This is a standard catalog part, not a last-time-buy or NRND item.","metaTitle":"TCAN4551RGYRQ1 CAN FD Controller, AEC-Q100, Active","metaDescription":"TI TCAN4551RGYRQ1 CAN FD Controller in 20-VQFN package.
