Functional safetyFunctional Safety-Capable
LifecycleActive
In one sentence: TI lists AEC-Q100 Grade 1 over -40 to +125°C. Package, temperature and configuration can vary by OPN; verify the exact orderable before ordering. TI lists Functional Safety-Capable with functional-safety documentation. The system ASIL claim still requires ECU-level verification.

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

Is SN6505B-Q1 automotive qualified?

TI lists AEC-Q100 Grade 1 over -40 to +125°C. Package and temperature can differ by OPN; verify the ordering table and TI datasheet.

Which OPNs are available for SN6505B-Q1?

TI's product page currently lists 2 OPNs; this page shows the first 2 OPNs, including SN6505BQDBVRQ1、SN6505BQDBVTQ1. Use the full OPN for ordering, not the GPN.

Where can I check price, stock and lead time for SN6505B-Q1?

NuAxi does not invent stock or pricing on this page. Use TI's ordering page and authorized distributors for live stock, lead time and quotations; verify package, temperature, pinout and software before substitution.
