O919A14CTRGZRQ1

Overview

The O919A14CTRGZRQ1 is an automotive-grade Power Management Unit (PMU) from the TPS65919 series, designed for processor applications. It operates within an input voltage range of 3.135 V to 5.25 V and supports output voltages from 1 V to 3.3 V. The device features four buck converters and integrates LDO regulators, delivering a total output current capability of 7 A. Packaged in a 48-pin VQFN with exposed pad, it is qualified to AEC-Q100 standards and functions reliably across a temperature range of -40°C to +105°C.

Feature Summary

• Integrated power management solution combining multiple buck converters and low-dropout regulators for complex processor systems.
• Automotive qualification ensuring reliability and performance under strict environmental and operational conditions.
• Compact surface-mount packaging designed to minimize board space requirements in dense electronic assemblies.

Applications

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

Procurement Notes

Verify the specific suffix 'C' against official Texas Instruments documentation to confirm exact pin-to-pin compatibility and functional variations compared to other variants like 'E'. Ensure the component meets AEC-Q100 grade requirements for your target automotive application environment. Cross-reference the datasheet revision date to validate parameter accuracy before finalizing design integration.

Selection Notes

Select this PMU when designing for TDA3x, DRA71x, or DRA79x processors requiring integrated power sequencing. The device suits applications needing multiple regulated rails from a single 3.135 V to 5.25 V source. Consider the 48-VQFN package constraints and thermal dissipation capabilities relative to the 7 A total load requirement.

Part Context

This component belongs to the TPS65919 family of specialized PMICs intended for high-performance automotive processing units. It consolidates power conversion functions typically handled by discrete components, reducing system complexity. The part is engineered specifically for Texas Instruments' automotive SoC ecosystems, providing optimized power delivery characteristics.

Replacement Considerations

The O919A14ETRGZRQ1 is a documented alternative within the same TPS65919 series. Verify if the 'E' suffix variant offers identical electrical specifications and pinout compatibility for your specific circuit design before substitution.
