O917A133TRGZTQ1

Overview

The O917A133TRGZTQ1 is an automotive-grade Power Management Unit (PMU) from the TPS65917 series, manufactured by Texas Instruments. It operates within a supply voltage range of 3.15 V to 5.25 V and features five integrated buck converters capable of delivering up to 5 A per channel. The device is housed in a 48-pin VQFN package and is qualified under the AEC-Q100 standard for automotive applications. It supports operating temperatures from -40°C to +105°C and provides regulated output voltages ranging from 700 mV to 3.3 V.

Feature Summary

• Integrates five independent high-current buck converters for flexible power distribution
• Automotive qualification ensures reliability in demanding vehicle environments
• Supports multiple digital communication interfaces for system configuration

Applications

• DRA72x processor platforms
• TDA3x video processing devices
• DRA76xP and DRA77xP processors
• TDA2Px systems

Procurement Notes

Verify the specific suffix against official documentation to confirm pinout and functional variations. Ensure the component meets AEC-Q100 requirements for your target automotive application. Confirm thermal management strategies align with the VQFN-48 package specifications.

Selection Notes

Select this PMU when designing systems based on DRA or TDA processors requiring multiple regulated rails. Evaluate the total current demand across all five buck channels to ensure it remains within the 5 A limit per converter. Consider the input voltage range compatibility with the system's primary power source.

Part Context

This component belongs to the TPS65917 family of specialized PMICs designed for complex embedded systems. These units consolidate multiple power stages into a single package to reduce board space and simplify power sequencing for high-performance processors.

Replacement Considerations

Consult official substitution lists for variants such as O917A14DTRGZTQ1 or O917A152TRGZRQ1. Verify that any alternative part maintains identical pin assignments and electrical characteristics before integration.
