RT9752AGQWF

Overview

The RT9752AGQWF is a USB interface integrated circuit combining a USB-C controller and power switch with high voltage protection. It supports the USB-C 2.0 standard and operates within a supply voltage range of 4.5 V to 5.5 V. The device features a working power current capacity of 3 A and functions reliably across an operating temperature range from -40 °C to +105 °C. Packaged in a WQFN-20 format for surface mount installation, it addresses humidity sensitivity requirements.

Feature Summary

Integrates USB-C controller functionality with a dedicated power switch
Provides built-in high voltage protection mechanisms
Supports USB-C 2.0 interface standards

Applications

USB-C port implementations requiring integrated control and switching

Procurement Notes

Verify component authenticity through authorized Richtek distributors or certified suppliers. Confirm package integrity and moisture barrier packaging status due to humidity sensitivity classification. Cross-reference ordering part numbers against official datasheets to ensure correct suffix alignment. Request RoHS compliance documentation and material declarations prior to final procurement authorization.

Selection Notes

Evaluate thermal performance requirements against the specified -40 °C to +105 °C operating range. Assess PCB layout constraints for the WQFN-20 package dimensions. Ensure system voltage levels remain within the 4.5 V to 5.5 V operational limits. Consider integration benefits of combined controller and switch topology versus discrete component approaches.
