TLIN1029-Q1

LIN transceiver with wake-up and protection

A physical layer for low-speed single-wire 12V automotive networks, transmitting up to 20kbps. Its 100kbps receive capability is for in-line programming, not a 100kbps LIN network; include TI's duty-cycle errata in compliance review.

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. No TI functional-safety category was established in the reviewed product parameters/features. This does not prove that related documents are unavailable; do not infer ASIL or Compliant status.

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

Why not call it a 100kbps LIN part?

100kbps describes receive-side programming. LIN transmission remains up to20kbps. State direction, purpose and conditions separately.

Is a LIN2.2A label enough for compliance?

No. Check supply, timing, bus loading and TI SLLA490 duty-cycle errata. A protocol list is not system qualification.

How should I verify the TLIN1029-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.
