O917A131TRGZRQ1

Overview

The O917A131TRGZRQ1 is an automotive-grade Power Management Unit (PMU) from the TPS65917-Q1 series, designed for processor applications. It operates within a 3.15 V to 5.25 V input voltage range and features five integrated buck converters capable of delivering up to 5 A total output current. The device supports output voltages ranging from 700 mV to 3.3 V. It is qualified under AEC-Q100 standards and functions reliably across a temperature range of -40°C to +105°C. The component is housed in a 48-pin VQFN package.

Feature Summary

• Integrates multiple power rails into a single compact unit for system simplification
• Automotive qualification ensures reliability in demanding vehicle environments
• Supports flexible voltage regulation for various processor core and peripheral requirements

Applications

• DRA72x processors
• TDA3x processors

• TDA2Px processors

Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm exact electrical characteristics and packaging options. Ensure compatibility with target processor families such as DRA or TDA series before integration. Confirm that the automotive grade meets the functional safety requirements of the intended application environment.

Selection Notes

Select this PMU when designing systems based on Texas Instruments Sitara or DRA processors requiring consolidated power management. Consider the thermal performance of the VQFN-48 package relative to the board layout. Evaluate the total current capacity of the five buck converters against the peak load demands of the connected processor and peripherals.

Part Context

This component belongs to the TPS65917-Q1 family of automotive power management units. These devices are engineered to replace discrete power solutions, reducing board space and complexity. The family is widely used in advanced driver assistance systems (ADAS) and infotainment platforms where high reliability and precise power sequencing are critical.

Replacement Considerations

Consult official substitution guides for compatible alternatives within the TPS65917 series. Verify pin-to-pin compatibility and electrical parameter alignment before replacing existing inventory.
