AOZ5276QI-01

Overview

The AOZ5276QI-01 is a high-power Smart Power Stage (SPS) module manufactured by Alpha & Omega Semiconductor Inc. It integrates two asymmetrical MOSFETs and an intelligent driver within a compact 39-pin QFN package measuring 5 mm x 6 mm. The device supports a peak output current of 90A and operates with load voltages ranging from 3V to 20V. Key integrated features include an IMON signal with 5mV/A gain and a TMON signal with 8mV/C gain, facilitating precise monitoring in space-constrained power conversion designs.

Feature Summary

• Integrates asymmetrical MOSFETs and driver for synchronous buck applications
• Provides analog current monitoring via IMON pin with defined gain
• Includes thermal monitoring capability through the TMON signal
• Supports PWM control and overcurrent protection settings

Applications

• Space-constrained synchronous buck converters
• High-density point-of-load (POL) regulation
• Server and storage power management systems

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status prior to integration. Ensure ESD handling protocols are followed during assembly. Check datasheet revisions for any updates to electrical characteristics or recommended operating conditions before finalizing design specifications.

Selection Notes

Select this module when high current density is required in a minimal footprint. Evaluate thermal performance requirements against the 5mm x 6mm package capabilities. Consider the integrated monitoring outputs if system diagnostics are necessary. Verify input voltage ranges match the 3V to 20V specification for the target application.

Part Context

This component belongs to the AOZ52xx series of Smart Power Stages from Alpha & Omega Semiconductor. These modules are designed to replace discrete MOSFET and driver combinations, reducing board space and simplifying layout. The series targets high-efficiency power conversion needs in modern electronic equipment requiring compact form factors.

Replacement Considerations

Direct substitutes may include other SPS modules from Alpha & Omega such as the AOZ5273QI-01 or AOZ5276QI. Verify pin compatibility and electrical ratings before substitution. Cross-reference package dimensions to ensure mechanical fit within the existing PCB layout constraints.
