In one sentence: TI's product page states AEC-Q100 Grade 1. NVM configuration and power sequencing vary by OPN; verify the exact orderable before design release. TI provides documentation to aid ISO 26262 system design up to ASIL-D. This is component-level functional-safety support, not a certificate that the end system is ASIL-D.

Orderable variants (OPNs)

The GPN is for selection; the OPN is the ordering unit. The table shows visible OPNs from TI's product page. NVM configuration and sequencing may differ; verify on TI's ordering page before purchase.

FAQ

Is TPS6594-Q1 automotive qualified?

Yes. TI's product page lists AEC-Q100 Grade 1 and an ambient range of –40°C to +125°C. Verify NVM configuration and sequencing for the exact OPN.

How do TPS6594-Q1 and LP8764-Q1 compare?

Both target automotive processor power, but output count, sequencing, package and companion processors differ. Start with the processor's rail/current/sequence requirements, then confirm with TI tools or an FAE.

Does Functional Safety-Compliant mean ASIL-D certified?

No. It means TI provides ISO 26262-oriented documentation such as FIT/FMEDA to support system design up to ASIL-D. The end system's ASIL-D claim depends on the vehicle/ECU safety concept and verification.
