RT9715DGBR

Overview

The RT9715DGBR is a single-channel N-channel power switch manufactured by Richtek USA Inc., designed for USB applications. It operates within a load voltage range of 2.7V to 5.5V and supports a maximum output current of 2A. The device features a typical on-resistance of 90 milliohms and utilizes an SOT-23-5R package. It includes integrated protection mechanisms such as fixed current limiting, thermal shutdown, reverse current blocking, and under-voltage lockout. The component functions with a non-inverted input interface and provides status flag outputs.

Feature Summary

• Integrated N-channel MOSFET with low on-resistance for efficient power switching
• Comprehensive fault protection including over-current, thermal shutdown, and reverse current blocking
• Open-drain fault flag output for system monitoring and diagnostics
• Designed for hot-plug applications with soft-start capability

Applications

• USB port power switching
• Portable battery-operated equipment
• Bus-powered USB devices

Procurement Notes

Verify the specific suffix 'DGBR' against official manufacturer documentation to confirm pinout and electrical specifications, as suffixes often denote package variations or tape-and-reel configurations. Confirm end-of-life status and lead times through authorized distributors, as availability may be limited for discontinued components. Ensure compatibility with existing PCB footprints and design requirements before procurement.

Selection Notes

Select this component for designs requiring high-side switching with integrated protection in compact packages. Consider the 2A current rating and 90mΩ on-resistance for efficiency needs. Evaluate the operating temperature range and protection features against application stress conditions. Verify that the SOT-23-5R package fits the board space constraints and that the open-drain flag interface matches the system control logic.
