RT9715FGB

Overview

The RT9715FGB is a single N-channel high-side power switch IC designed for USB applications. It features a typical on-resistance of 90mΩ and supports an operating voltage range of 2.7V to 5.5V. The device provides a maximum output current of 1.5A and includes integrated fault protection mechanisms such as over-current, thermal shutdown with foldback, reverse blocking, and under-voltage lockout. It utilizes a non-inverting open/switch interface and offers a status flag output. The component is housed in a WDFN-8 package.

Feature Summary

Integrates a low on-resistance N-MOSFET switch for efficient power delivery
Includes comprehensive fault protection against over-current, thermal events, and reverse current
Provides a deglitched status flag for accurate fault reporting

Applications

USB peripheral power switching
Notebook PC power distribution
Portable electronic device load drivers

Procurement Notes

Verify the specific suffix 'FGB' against official Richtek documentation to confirm the exact package type and tape/reel specifications. Confirm end-of-life status and availability through authorized distributors, as this series may have discontinued variants. Ensure compatibility with required PCB footprint dimensions for the WDFN-8 package.

Selection Notes

Select this component when a cost-effective, single-channel high-side switch is required for USB loads. Consider the 90mΩ on-resistance for efficiency needs and the 1.5A current rating for load capacity. Verify that the WDFN-8 package fits the design constraints and that the non-inverting control logic matches the system interface requirements.

Part Context

The RT9715 series comprises low-voltage, single N-MOSFET high-side power switches optimized for USB applications. These devices are characterized by low on-resistance and low supply current. The family includes various current ratings and package options to support different power and space requirements in portable electronics and computer peripherals.
