AOZ1327DI-02

Power Distribution Switches, Load Drivers Overview

The AOZ1327DI-02 is a single-channel N-channel power switch designed for USB applications. It operates with a load voltage range of 3.4V to 22V and supports a maximum continuous output current of 8A. The device features a typical on-resistance of 20 milliohms and utilizes a 12-DFN (3x3) surface-mount package. It includes integrated fault protection mechanisms such as over-temperature, over-voltage, short-circuit, and under-voltage lockout. The component functions within an ambient temperature range of -40°C to 85°C.

Power Distribution Switches, Load Drivers Feature Summary

• Power distribution units

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix '02' against the manufacturer datasheet to confirm packaging and reel specifications. Ensure the 12-DFN footprint matches the target PCB design. Confirm RoHS3 compliance requirements align with project standards. Check for any recent product change notices affecting pinout or electrical characteristics before finalizing procurement.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when a single-channel high-current switch is required for USB interfaces. The 20 milliohm on-resistance minimizes power loss during conduction. Integrated protections reduce external component count compared to discrete solutions. Verify that the 22V maximum load voltage exceeds the system's peak operating voltage to ensure reliable operation under all conditions.

Power Distribution Switches, Load Drivers Part Context

This part belongs to the AOZ1327 family of power switches from Alpha & Omega Semiconductor. It is distinct from MOSFETs like the AOD950A70 by integrating control logic and protection directly into the IC. Unlike the AOZ1300AI, it supports higher voltages up to 22V and higher currents up to 8A. The 12-DFN package offers a compact solution for space-constrained designs.

Power Distribution Switches, Load Drivers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternatives based on matching 8A current rating, 20mΩ Rds(on), and 12-DFN package compatibility. Verify that replacement devices offer equivalent fault protection features and USB-specific characteristics.
