RT9471GQW(2)

Overview

The RT9471GQW(2) is a single-cell lithium-ion switching battery charger manufactured by Richtek USA Inc. It supports a maximum charging current of 3A and operates with an input voltage up to 13.5V. The device features a programmable constant-current/constant-voltage (CC/CV) charging profile, integrated power path management for system load prioritization, and USB-OTG boost mode capability. It utilizes a 24-pin WQFN package suitable for surface-mount assembly.

Feature Summary

Integrated power path management for efficient system operation
Supports USB-OTG boost mode for host functionality
Programmable charging parameters via external components

Applications

Smartphones and mobile phones
Tablets and portable media players
Handheld gaming devices
Portable medical equipment

Procurement Notes

Verify the specific suffix GQW(2) against the official datasheet to confirm pinout and thermal pad configuration. Ensure compatibility with the target PCB footprint and reflow soldering profile. Confirm RoHS compliance status through the manufacturer's declaration before integration into regulated products.

Selection Notes

Select this component for applications requiring high-efficiency single-cell charging with integrated power path management. Consider the 24-pin WQFN package size constraints and thermal dissipation requirements. Evaluate the need for USB-OTG functionality and programmable charging profiles relative to system design goals.

Part Context

This part belongs to Richtek’s RT947x series of single-cell lithium-ion battery chargers. The series is designed for portable consumer electronics, offering compact solutions with integrated power path management. The RT9471 variant specifically provides 3A charging capability within a small form factor.

Replacement Considerations

RT9466GQW: Similar 5A single-cell charger with power path management but higher current rating. Verify package compatibility and current requirements. RT9470WSC: 3A single-cell charger in WLCSP package; requires different PCB layout due to package change.
