AOZ1353LI-02

Power Distribution Switches, Load Drivers Overview

The AOZ1353LI-02 is a single-channel N-channel power distribution switch designed for USB Type-C applications. It operates with an input voltage range of 3.4V to 5.5V and supports a load voltage up to 28V. The device provides programmable current limiting and over-voltage protection, featuring true reverse-current blocking capabilities. Packaged in a compact 12-WLCSP (1.81x1.31mm) format, it integrates high-side switching functionality without requiring a separate Vcc supply.

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix '02' against official Alpha & Omega Semiconductor documentation to confirm pinout and marking compatibility. Ensure the WLCSP package dimensions align with your PCB footprint requirements. Confirm that the 28V output tolerance meets your system's transient voltage specifications before finalizing procurement.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when designing USB Type-C interfaces requiring integrated protection features. The absence of a required Vcc supply simplifies board layout compared to switches needing external logic levels. Verify that the 3.5A continuous current rating suffices for the target application's peak load demands while ensuring the 12-WLCSP package fits within the available space constraints.

Power Distribution Switches, Load Drivers Part Context

This part belongs to the ECPower™ Protection Switch family from Alpha & Omega Semiconductor. It is engineered for low-profile applications where space is limited. The series emphasizes integration by combining switching, current limiting, and protection functions into a single small-footprint package suitable for modern mobile and consumer electronics.

Power Distribution Switches, Load Drivers Replacement Considerations

Check official substitution lists for compatible devices within the same AOSMD portfolio. Ensure any alternative maintains the 12-WLCSP package and 28V output tolerance. Verify that replacement parts offer equivalent reverse-current blocking and programmable current limit settings to maintain system safety.
