RT9715CGQW

Overview

The RT9715CGQW is a single N-channel high-side power switch IC designed for USB peripheral applications. It integrates an N-MOSFET with a typical on-resistance of 90mΩ and operates within a voltage range of 2.7V to 5.5V. The device features comprehensive protection mechanisms including over-current protection, thermal shutdown with foldback, reverse blocking current capability, and under-voltage lockout. It provides a deglitched fault flag output and requires no supply voltage. Packaged in an SOT-23-5R format, it supports surface mount installation.

Feature Summary

Integrates a low on-resistance N-MOSFET switch for efficient power delivery
Includes built-in thermal protection with foldback current limiting
Provides a deglitched fault status flag for system monitoring
Supports reverse blocking current to prevent backflow

Applications

USB peripheral power switching
Notebook PC power distribution
High-side load driver circuits

Procurement Notes

Verify the specific suffix CGQW against official Richtek documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the component matches the intended high-side switch application parameters before procurement.

Selection Notes

Select this component when a cost-effective, low-voltage high-side switch is required for USB interfaces. Consider its 90mΩ on-resistance for efficiency needs and verify that the 2A current rating aligns with the load requirements. Evaluate the integrated protection features against the specific safety standards of the target electronic equipment.

Part Context

The RT9715 series comprises single N-channel high-side power switches optimized for USB applications. These devices are part of Richtek's portfolio of power management solutions, focusing on providing robust protection and low conduction losses in compact packages suitable for portable electronics and computer peripherals.
