Procurement Notes

Verify the complete part number including suffixes against official Texas Instruments documentation to ensure correct package, temperature grade, and tape-and-reel specifications. Confirm AEC-Q100 qualification status and RoHS compliance requirements prior to integration into automotive designs. Cross-reference application notes for DRA71x, TDA3x, or DRA79x platforms to validate compatibility with specific system power sequencing needs.

Selection Notes

Select this component when designing systems based on DRA71x, TDA3x, or DRA79x processors requiring integrated automotive-grade power regulation. Ensure input voltage constraints between 3.135 V and 5.25 V align with the system bus architecture. Consider the 48-VQFN footprint for PCB layout constraints and verify thermal dissipation capabilities within the specified -40°C to +105°C ambient operating range for automotive durability.

Part Context

This PMU belongs to the TPS65919 family, specialized for automotive applications. It serves as a central power management hub for Texas Instruments Sitara and Jacinto processors. The device consolidates multiple power rails into a single integrated circuit, reducing component count and board space compared to discrete solutions.
