RT9715EGF

Overview

The RT9715EGF is a cost-effective, low-voltage, single N-MOSFET high-side power switch IC designed for USB applications. It features an 8-MSOP package and supports a load voltage range of 2.7V to 5.5V. The device provides a maximum output current of 1.1A with a typical on-resistance of 90 milliohms. It includes integrated protection mechanisms such as fixed current limiting, over-temperature shutdown, reverse current blocking, and under-voltage lockout (UVLO). Additional functional features include load discharge and a status flag output. The component operates within a junction temperature range of -40°C to 100°C.

Feature Summary

• Integrates a single N-channel MOSFET in a high-side configuration for efficient power distribution.
• Provides comprehensive fault protection including fixed current limiting, thermal shutdown, and reverse current blocking.
• Includes a status flag output to indicate operational state or fault conditions.
• Supports rapid load discharge to ensure safe system shutdown.

Applications

• USB port power switching and protection
• Portable electronic device power management
• Peripheral power distribution circuits

Procurement Notes

Verify the specific suffix 'EGF' corresponds to the 8-MSOP package variant when sourcing. Confirm RoHS compliance status through official manufacturer declarations. Check for end-of-life notifications or obsolescence notices from Richtek USA Inc. prior to finalizing procurement plans. Ensure compatibility with surface-mount assembly processes suitable for the MSOP footprint.

Selection Notes

Select this component for applications requiring a compact, high-side USB power switch with integrated protection. Consider the 1.1A current limit and 90mΩ on-resistance for efficiency requirements. Evaluate the need for a status flag and load discharge functionality against system design constraints. Compare against alternative packages if space limitations differ from the 8-MSOP form factor.

Part Context

The RT9715 series comprises low-voltage power switches optimized for USB interfaces. The RT9715EGF specifically denotes the version packaged in an 8-pin Mini-SOP. This family offers a balance of performance and cost for consumer electronics. Other variants in the series may differ in package type or current ratings while maintaining similar core protection features.
