RT9715EGBR

Overview

The RT9715EGBR is a single N-channel MOSFET high-side power switch IC designed for USB applications. It features a low typical on-resistance of 90mΩ and supports a load voltage range of 2.7V to 5.5V with a maximum output current of 1.1A. The device integrates fixed current limiting, over-temperature protection, reverse current blocking, and under-voltage lockout (UVLO). It operates within a junction temperature range of -40°C to 100°C and is housed in an SOT-23-5 package.

Feature Summary

Integrates a single N-channel MOSFET with low on-resistance for efficient power switching.
Includes comprehensive fault protection mechanisms such as fixed current limit, thermal shutdown, and reverse current blocking.
Provides status flag indication for monitoring switch conditions.

Applications

USB port protection
Portable electronics power distribution
Smartphone peripheral interfaces

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to obsolete status. Confirm RoHS compliance and MSL rating prior to integration. Check for valid EOL documentation and last-time buy availability if required for long-term production support.

Selection Notes

Select this component for cost-effective USB power management requiring high-side switching. Ensure the application load does not exceed the 1.1A current limit. Verify that the system voltage remains within the 2.7V to 5.5V operating range. Consider the SOT-23-5 footprint constraints during PCB layout design.

Part Context

The RT9715 series comprises low-voltage power switches optimized for portable devices. This specific model represents a single-channel variant within the family, focusing on USB interface protection. It serves as a compact solution for managing power delivery in space-constrained mobile applications.
