O9038A352IZWSRQ1

Overview

The O9038A352IZWSRQ1 is an automotive-grade Power Management Unit (PMU) from the TPS659038-Q1 series, designed for ARM Cortex-A15 processors. It integrates seven buck converters and eleven low-dropout regulators (LDOs). The device operates within an input voltage range of 3.135 V to 5.25 V. Output voltages are adjustable from 700 mV to 3.3 V. It supports a maximum output current of 6 A. The component is qualified to AEC-Q100 standards and functions between -40°C and +85°C. It utilizes a 169-pin NFBGA package.

Feature Summary

• Integrates seven high-current buck converters and eleven LDOs for comprehensive power rail generation.
• Automotive qualification compliant with AEC-Q100 standards for reliability in vehicle environments.
• Optimized specifically for powering complex ARM Cortex-A15 processor architectures.

Applications

• Powering AM572x processor systems
• Automotive infotainment platforms
• Digital cockpit controller units

Procurement Notes

Verify the specific suffix against the manufacturer's official documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the AEC-Q100 qualification status matches your project's automotive reliability requirements. Ensure the NFBGA-169 footprint aligns with your PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this PMIC when designing systems requiring multiple regulated rails for high-performance automotive processors. It consolidates discrete components into a single solution, reducing board space. Consider the thermal performance of the NFBGA package relative to your system's heat dissipation capabilities. Verify compatibility with the target processor's power-up sequencing requirements.

Part Context

This part belongs to the TPS659038-Q1 family of specialized power management ICs. It serves as a direct counterpart to similar multi-rail solutions but is distinct from the TPS659039 series. The O9038 variant provides a specific configuration of buck and LDO outputs tailored for automotive applications requiring robust power integrity.

Replacement Considerations

The O9039A352IZWSRQ1 is a related variant within the same family. Verify if the additional LDO count or specific output configurations of the O9039 series meet your design needs. Cross-reference pinouts and electrical characteristics carefully to ensure functional equivalence without redesigning the power stage.
