TCAN1043A-Q1

CAN FD transceiver with INH power control

Sleep, WAKE and INH allow external supplies to be gated during node sleep. INH controls an enable signal rather than regulating power, and A/AT variants have different data-rate limits.

LifecycleActive
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

Can INH power the MCU?

Do not treat INH as an LDO. It enables an external regulator; MCU supply remains an external power-design task.

Can 150°C imply Grade 0?

No. Junction temperature, ordering range and AEC grade are separate fields. The reviewed source does not state a common numeric grade; we do not infer one.

How should I verify the TCAN1043A-Q1 orderable?

The page lists 5 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.
