O917A154TRGZTQ1

Overview

The O917A154TRGZTQ1 is an automotive-grade Power Management Unit (PMU) from the TPS65917-Q1 series, manufactured by Texas Instruments. It operates within an input voltage range of 3.15 V to 5.25 V and features five buck converters and five low-dropout (LDO) regulators. The device supports a maximum output current of 7 A and provides adjustable output voltages ranging from 700 mV to 3.3 V. Designed for high integration in automotive camera modules, it utilizes a 48-pin VQFN package and meets AEC-Q100 qualification standards for operation between -40°C and +105°C.

Feature Summary

• Highly integrated power management solution designed specifically for automotive camera modules
• Combines multiple switching regulators and LDOs to reduce component count and board space
• Automotive qualification ensuring reliability under harsh environmental conditions

Applications

• Automotive camera modules
• ADAS sensor power systems
• In-vehicle infotainment power distribution

Procurement Notes

Verify the complete part number including suffixes such as TRGZTQ1 to ensure correct packaging and temperature grade. Confirm AEC-Q100 compliance requirements match your specific automotive application standards. Check for moisture sensitivity level handling instructions during assembly. Ensure compatibility with the TPS65917EVM development kit if prototyping. Validate that the 48-VQFN footprint matches your PCB design constraints.

Selection Notes

Select this PMU when designing automotive vision systems requiring consolidated power regulation. It is suitable for applications needing multiple voltage rails from a single IC. Consider its thermal performance in enclosed automotive environments. Evaluate the 7 A total current capability against system load requirements. Ensure the 3.15 V to 5.25 V input range aligns with vehicle battery or supply characteristics.

Part Context

This component belongs to the TPS65917-Q1 family of specialized power management ICs. It serves as a processor and peripheral power solution for Texas Instruments automotive processors like the DRA7xx and TDA2xx/3xx series. The device integrates control logic with power stages to simplify system architecture. It replaces discrete regulator solutions in complex automotive electronic control units.

Replacement Considerations

Consult official substitution guides for equivalent PMICs within the TPS6591x family. Verify pin-to-pin compatibility before replacing with variants like O917A130TRGZRQ1. Ensure functional equivalence for all five buck and five LDO outputs. Confirm identical automotive qualification status for safety-critical applications.
