AOZ1353DI-02

Power Distribution Switches, Load Drivers Overview

The AOZ1353DI-02 is a smart current-limited load switch manufactured by Alpha & Omega Semiconductor Inc. It features an N-channel configuration with a continuous current rating of 3.5A. The device operates within an input voltage range of 3.4V to 5.5V and is housed in a compact 12-DFN (3x3 mm) surface-mount package. This integrated circuit provides comprehensive protection mechanisms for downstream loads.

Power Distribution Switches, Load Drivers Feature Summary

• Integrates adjustable current limiting functionality to protect circuits from overcurrent conditions
• Includes latch function for persistent fault state management until reset
• Provides multi-layer protection against overvoltage, undervoltage, overtemperature, and short circuits

Power Distribution Switches, Load Drivers Applications

• USB Type-C port power sourcing applications
• Current-limited load switching for sensitive electronic loads
• Overvoltage protection switches in portable devices

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix -02 to confirm the 3.4V-5.5V operating range and DFN-12L package variant. Confirm RoHS3 compliance status as required by your assembly specifications. Ensure the design supports the latch function behavior if used in fault-protection scenarios. Check for obsolescence notices as availability may vary.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when a compact solution for USB Type-C or similar low-voltage interfaces is required. The 3.5A rating suits moderate load applications. The adjustable current limit allows customization for different load profiles. The small 3mm x 3mm footprint is ideal for space-constrained designs requiring integrated protection features.

Power Distribution Switches, Load Drivers Part Context

This part belongs to the AOSMD ECPower series of smart load switches. It is designed to replace discrete protection components by integrating multiple safety functions into a single IC. The device targets modern consumer electronics and mobile accessories where size and reliability are critical constraints.

Power Distribution Switches, Load Drivers Replacement Considerations

Direct substitutes include other variants within the AOZ1353 family such as AOZ1353DI-05 or AOZ1353DI-06, provided their specific voltage ranges and pinouts match the application requirements. Verify electrical parameters before substitution.
