RT9728AHGQW

Overview

The RT9728AHGQW is a single P-channel MOSFET high-side power switch IC designed for USB applications. It operates within a voltage range of 2.5V to 5.5V and supports an output current of up to 1.3A. The device features a maximum on-resistance of 120mΩ and includes programmable current limiting, overtemperature protection, and UVLO. It is housed in a compact 6-pin WDFN package.

Feature Summary

Integrates a single P-channel MOSFET for high-side switching
Provides programmable current limit protection
Includes status flag indication for fault monitoring

Applications

USB port power distribution
Portable electronic device power management
Overcurrent protection circuits

Procurement Notes

Verify the specific suffix 'QG' or 'QW' against the manufacturer's official datasheet to confirm pinout compatibility and thermal pad requirements. Ensure the selected variant matches the required operating temperature range and packaging specifications for your design.

Selection Notes

Select this component for low-voltage USB applications requiring integrated current limiting and status feedback. Compare the 1.3A current rating and 120mΩ on-resistance against load requirements. Consider the WDFN package size constraints and thermal dissipation capabilities relative to the PCB layout.

Part Context

This part belongs to the Richtek RT9728 family of USB power switches. It serves as a cost-effective solution for protecting downstream loads from overcurrent conditions while providing a simple interface for power control and status monitoring in portable electronics.

Replacement Considerations

The RT9728AHGE is a similar SOT-23-6 packaged variant with identical electrical characteristics. Verify package footprint differences when substituting.
