TCAN1044A-Q1

CAN FD transceiver with standby wake-up

Provides physical-layer signaling and standby wake for an existing CAN controller, not CAN-frame scheduling. VIO translation is an AV-variant feature; validate 8Mbps against the actual network topology.

In one sentence: Qualification is grounded in this TI product's documentation; no grade is inferred from temperature. An ordering table may show junction or variant-specific limits, which must be distinguished from ambient conditions. TI explicitly lists Functional Safety-Capable. This is a device-documentation category, not system ASIL certification; assess the exact function, assumptions and safety manual.

Orderable variants (OPNs)

The GPN is for selection; the full OPN is for ordering. These examples were observed on the verification date, not live stock. Variants may differ in package, temperature, gain/threshold and, for PMICs, NVM/sequencing. Distinguish TA from TJ in the exact datasheet.

FAQ

What changes between A and AV variants?

AV provides VIO level translation. Check exact-OPN logic levels and pins instead of applying AV capability to every A variant.

Does an 8Mbps transceiver make the network 8Mbps?

No. Controller capability, node count, cable length, stubs and EMC requirements all constrain rate; TI qualifies 8Mbps for simpler networks.

How should I verify the TCAN1044A-Q1 orderable?

The page lists 6 OPN examples from official material checked on 2026-11-06. Match package, function options and temperature definitions; obtain live price/stock from TI or authorized distributors.
