O917A154TRGZRQ1

Overview

The O917A154TRGZRQ1 is an automotive-grade Power Management IC (PMIC) from the TPS65917 series, designed for complex processor power architectures. It operates within an input voltage range of 3.15 V to 5.25 V and delivers a total output current of 7 A. The device integrates five buck converters and five low-dropout (LDO) regulators, with adjustable output voltages ranging from 700 mV to 3.3 V. Qualified under AEC-Q100 standards, it functions reliably between -40°C and +105°C. Packaged in a 48-pin VQFN (RGZ) format, it supports applications including DRA72x, TDA3x, DRA76xP, DRA77xP, and TDA2Px processors.

Procurement Notes

Verify the specific suffix code against official Texas Instruments documentation to confirm exact electrical tolerances and package variations. Ensure compatibility with the target processor's power sequencing requirements. Confirm that the VQFN-48 thermal characteristics meet the system's heat dissipation design constraints before finalizing procurement specifications.

Selection Notes

Select this component when designing automotive systems requiring a single-chip solution for multiple voltage rails. It is suitable for applications needing both high-current switching regulation and low-noise linear regulation. Consider the 48-pin VQFN footprint for PCB layout constraints. Validate that the 3.15 V to 5.25 V input range aligns with the vehicle's power supply architecture.

Part Context

This part belongs to the TPS65917 family of PMUs, which are specialized for Texas Instruments' Sitara and Jacinto processor families. These devices consolidate multiple power stages into a single package to reduce board space and simplify power management design for advanced automotive and industrial applications.

Replacement Considerations

Consult official substitution guides for variants such as O917A130TRGZRQ1 or O917A14DTRGZRQ1. Verify pin-to-pin compatibility and electrical parameter alignment before swapping components in existing designs.
