AOZ5117QI

Overview

The AOZ5117QI is a high-performance DrMOS power module manufactured by Alpha & Omega Semiconductor Inc. It integrates a half-bridge driver and synchronous MOSFETs into a single 31-PowerVFQFN package (5x5 mm). The device supports a maximum voltage of 25V and delivers an output current of 60A per channel. Designed for surface-mount installation, it features PWM interface control and operates within a junction temperature range of -40°C to 150°C. The module includes built-in fault protection mechanisms such as under-voltage lockout and over-current protection.

Feature Summary

• Integrates half-bridge driver and synchronous MOSFETs in a compact DrMOS configuration
• Supports high-current operation up to 60A with 25V voltage rating
• Includes integrated fault protection features like UVLO and over-current protection

Applications

• Synchronous buck converters
• High-density point-of-load regulation
• Server and workstation power supplies

Procurement Notes

Verify the specific suffix (e.g., QI) against the manufacturer's official datasheet to confirm pinout and electrical specifications. Ensure compatibility with existing PCB footprints for the 31-PowerVFQFN package. Confirm RoHS compliance status if required by project regulations. Check for any obsolescence notices or recommended replacement parts from Alpha & Omega Semiconductor before finalizing procurement plans.

Selection Notes

Select this component when a compact solution is needed for high-current synchronous buck applications. The integrated DrMOS design reduces board space and simplifies thermal management compared to discrete solutions. Verify that the 60A current rating meets the peak load requirements of the target application. Ensure the 25V input voltage range aligns with the system power rails.

Part Context

The AOZ5117QI belongs to Alpha & Omega Semiconductor's DrMOS family, which combines gate drivers and power switches for efficient power conversion. This series targets high-density power delivery systems where size and efficiency are critical. The 31-PowerVFQFN package provides robust thermal performance and reliable surface-mount integration for modern electronic designs.

Replacement Considerations

Check for AOZ5117QI-01 or AOZ5117QI-02 variants if different marking or packaging options are required. Verify electrical equivalence with other 60A/25V DrMOS modules from Alpha & Omega or competitors before substitution.
