RT9715FGS

Overview

The RT9715FGS is a single-channel N-channel power distribution switch manufactured by Richtek USA Inc. It operates within a load voltage range of 2.7V to 5.5V and supports a maximum output current of 700mA. The device features a typical on-resistance of 90 milliohms and utilizes an 8-SOIC surface-mount package. It includes integrated fault protection mechanisms such as fixed current limiting, over-temperature shutdown, reverse current blocking, and under-voltage lockout (UVLO). The component functions with a non-inverting open/switch interface and does not require a separate supply voltage.

Feature Summary

• Integrates high-side N-channel power switching for load driver applications
• Provides comprehensive fault protection including thermal shutdown and reverse current blocking
• Features a low on-resistance design for efficient power distribution
• Operates without a dedicated supply voltage requirement

Applications

• USB port power switching and protection
• Peripheral load drivers in consumer electronics
• High-side switching in portable devices

Procurement Notes

Verify the obsolete status of this component before procurement planning. Confirm availability through authorized distributors or secondary market sources. Ensure compatibility with existing PCB footprints and signal interfaces. Check for RoHS compliance documentation if required for specific regulatory standards. Consider lead times associated with end-of-life inventory.

Selection Notes

Select this component for applications requiring a single-channel high-side switch with integrated protection features. Evaluate the 700mA current limit against peak load requirements. Ensure the 2.7V to 5.5V operating range matches the system voltage rails. Verify that the 8-SOIC package dimensions fit the mechanical constraints of the design.
