AOZ7271DV

Overview

The AOZ7271DV is a single-channel active bridge power module manufactured by Alpha & Omega Semiconductor Inc. It integrates an N-channel MOSFET with an OR controller, functioning as an ideal diode rectifier. The device operates within a supply voltage range of 15.2V to 17V and draws a typical supply current of 22 µA. Designed for surface-mount installation, it utilizes a compact 4-DFN (8x8) package, also identified as 4-PowerTSFN. The component supports a maximum reverse voltage of 600V and handles currents up to 125A in specific configurations.

Feature Summary

• Integrates an N-channel MOSFET with an OR controller for active bridge applications
• Functions as an ideal diode rectifier with internal switching capability
• Features low quiescent current consumption for efficient power management

Applications

• General-purpose power distribution systems
• Ideal diode rectification circuits
• Active bridge power modules

Procurement Notes

Verify the exact package designation, as sources list both 4-DFN (8x8) and 4-PowerTSFN. Confirm RoHS3 compliance status prior to integration. Check for obsolescence notices, as some records indicate this part may be discontinued or restricted for new designs. Ensure the supplier documentation matches the specific suffix requirements for your assembly process.

Selection Notes

Select this component when a high-voltage, single-channel active bridge solution is required. The integrated OR controller simplifies design by eliminating external logic for ideal diode control. Consider the 4-DFN footprint for space-constrained layouts. Verify thermal performance requirements against the module's dissipation capabilities in the target application environment.
