RT9715DGF

Overview

The RT9715DGF is a single N-channel high-side power switch IC designed for USB applications. It operates with a load voltage range of 2.7V to 5.5V and features a typical on-resistance of 90mΩ. The device integrates fixed current limiting, over-temperature protection, reverse current blocking, and under-voltage lockout (UVLO). It includes load discharge functionality and a status flag output. The component supports an operating junction temperature from -40°C to 100°C and is available in an 8-MSOP package.

Feature Summary

• Integrates N-channel MOSFET with low on-resistance for efficient power switching
• Provides comprehensive fault protection including current limit, thermal shutdown, and reverse current blocking
• Includes active load discharge circuitry for rapid power-down
• Features status flag output for system monitoring

Applications

• USB port power management
• High-side load switching
• Portable electronic device power distribution

Procurement Notes

Verify the specific suffix 'DGF' against the manufacturer's official datasheet to confirm pinout and electrical characteristics match design requirements. Confirm end-of-life status and lead times with authorized distributors as availability may be limited. Ensure compatibility with existing PCB footprint and thermal management strategies during integration.

Selection Notes

Select this component for applications requiring a cost-effective, single-channel high-side switch with integrated protection features. Consider the 90mΩ on-resistance for efficiency calculations and verify that the 2A current capability meets load demands. Evaluate the 8-MSOP package constraints for space-limited designs.
