RT9715AGB

Overview

The RT9715AGB is a single N-channel high-side power switch IC designed for USB applications, manufactured by Richtek USA Inc. It features a typical on-resistance of 80mΩ and supports a continuous load current of 1.5A. The device operates within a voltage range of 2.5V to 5.5V and includes an open-drain fault flag output. Key protection mechanisms include thermal shutdown, under-voltage lockout (UVLO), and fixed current limiting. It is housed in a SOT-23-5 package.

Feature Summary

Built-in N-MOSFET with low on-resistance compliant with USB specifications
Open-drain fault flag output for status indication
Integrated soft-start to limit inrush current during hot plug-in
Reverse current flow blocking capability

Applications

Self-powered Universal Serial Bus (USB) applications
Bus-powered Universal Serial Bus (USB) applications
Portable battery-operated equipment

Procurement Notes

Verify component authenticity through authorized distributors or the manufacturer directly. Confirm the specific suffix corresponds to the SOT-23-5 package and lead-free RoHS compliance. Check for end-of-life status or obsolescence notices prior to procurement to ensure supply chain stability for production needs.

Selection Notes

Select this component for designs requiring a compact high-side switch with integrated fault reporting. Ensure the input voltage range aligns with the 2.5V to 5.5V specification. Consider the 1.5A current rating and 80mΩ resistance for voltage drop calculations. Verify that the SOT-23-5 package fits the board layout constraints.

Part Context

The RT9715 series comprises cost-effective, low-voltage power switches optimized for USB peripherals. This specific model represents the A variant within the family, distinguished by its 1.5A current rating and 80mΩ on-resistance in the SOT-23-5 package, differentiating it from higher current or different package variants like the RT9715BGBR.
