O919A14ETRGZTQ1

Overview

The O919A14ETRGZTQ1 is an automotive-grade Power Management Unit (PMU) from the TPS65919 series, manufactured by Texas Instruments. It integrates four high-current buck converters and multiple low-dropout regulators within a single VQFN-48 package. The device operates with an input voltage range of 3.135 V to 5.25 V and supports output voltages from 1 V to 3.3 V. Designed for harsh environments, it meets AEC-Q100 standards and functions reliably across a temperature range of -40°C to +105°C.

Feature Summary

• Integrates four independent buck converters and auxiliary LDOs for comprehensive power distribution
• Automotive qualification compliant with AEC-Q100 reliability standards
• Optimized for complex processor architectures in advanced driver assistance systems

Applications

• TDA3x processor platforms
• DRA71x processor platforms
• DRA79x processor platforms

Procurement Notes

Verify the specific suffix 'TQ1' confirms the tape-and-reel packaging format and automotive grade designation. Confirm that the required output current capabilities align with the system's peak load requirements. Ensure the VQFN-48 thermal pad soldering process matches the design guidelines provided in the official datasheet to maintain thermal performance.

Selection Notes

Select this component when designing for TDA3x or DRA7xx family processors requiring integrated power sequencing. Compare against the O917A14 variant if five buck converters are necessary instead of four. Evaluate the 48-pin form factor constraints against available PCB real estate. Verify compatibility with existing board layouts designed for the TPS65919 family.

Part Context

This part belongs to the TPS65919-Q1 family of specialized PMICs intended for automotive applications. It serves as a central power management solution for Texas Instruments Sitara and TDA processors. The device consolidates multiple power rails into a compact footprint, reducing bill-of-materials complexity compared to discrete regulator solutions.

Replacement Considerations

The O919A14ETRGZRQ1 is the commercial/industrial grade equivalent with identical electrical specifications but different operating temperature ranges. Cross-reference pinouts carefully when substituting with other TPS65919 variants.
