AOZ15333DI-02

Power Distribution Switches, Load Drivers Overview

The AOZ15333DI-02 is a current-limiting switch designed for USB Type-C pull-current applications, supporting up to 28V. It features a 3.5A current capability with a typical on-resistance of 45mΩ and operates within a 3.3V to 5.5V input voltage range. The device includes true reverse current blocking (TRCB), programmable current limiting, and slew rate control. It offers fast recovery from overvoltage and TRCB faults, with a static current of 125μA and shutdown current of 6μA. Protection mechanisms include overvoltage protection (OVP), input under-voltage lockout (UVLO), thermal shutdown (TSD), and ESD protection rated at ±2kV HBM and ±1kV CDM.

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix -02 indicates latch mode operation, distinguishing it from auto-restart variants. Confirm package integrity for the DFN-12L 3mm x 3mm form factor. Ensure compatibility with 28V Type-C EPR implementations. Check for UL 2367 and IEC 62368-1:2018 certification marks on documentation. Validate pinout alignment with target PCB layout requirements.

Power Distribution Switches, Load Drivers Selection Notes

Select this component for applications requiring robust protection in high-speed data and power interfaces. The latch mode (-02 suffix) is suitable where manual reset or system-level intervention is preferred after a fault. Consider the 45mΩ on-resistance for efficiency calculations at 3.5A loads. Evaluate the 125μA static current for always-on system constraints. Ensure the DFN-12L package fits the available board space.
