TCAN1145-Q1

CAN FD transceiver with partial networking

SPI-configured selective wake can reduce active nodes under supported wake-frame/network conditions. SPI does not mean an integrated CAN controller; watchdog and advanced diagnostics of 1144/1146 must not be attributed to 1145.

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

Does SPI remove the need for a CAN controller?

No. SPI configures the transceiver. CAN data-link control remains in the host or a separate controller.

Does TCAN1145 include the family's Q&A watchdog?

The reviewed family description assigns watchdog and advanced diagnostics to TCAN1144/1146, not TCAN1145. Selective wake is not watchdog supervision.

How should I verify the TCAN1145-Q1 orderable?

The page lists 3 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.
