RT9715FGBR

Overview

The RT9715FGBR is a single N-channel high-side power switch IC designed for USB applications, manufactured by Richtek USA Inc. It operates within a voltage range of 2.7V to 5.5V and features a typical on-resistance of 90mΩ. The device integrates fixed over-current protection, thermal shutdown with foldback, reverse current blocking, and under-voltage lockout. It provides a deglitched fault flag output and requires no supply voltage. Packaged in an SOT-23-5R (SC-74A) surface-mount package, it supports a maximum output current of 2A and functions across a junction temperature range of -40°C to 100°C.

Feature Summary

Integrates a low on-resistance N-MOSFET switch for efficient power delivery
Includes comprehensive fault protection mechanisms such as fixed over-current, thermal shutdown, and reverse current blocking
Provides a deglitched status flag output for accurate fault reporting

Applications

USB peripheral devices
Notebook PCs

Procurement Notes

Verify component authenticity through authorized distributors or the manufacturer directly. Confirm RoHS compliance and REACH status prior to integration. Check for End-of-Life (EOL) notifications, as availability may be limited. Ensure storage conditions adhere to Moisture Sensitivity Level (MSL) 3 requirements to prevent package damage during soldering.

Selection Notes

Select this component for designs requiring a cost-effective, low-voltage high-side switch with integrated protection. Consider the 90mΩ on-resistance for efficiency and the 2A current capability for load requirements. Verify that the SOT-23-5R package fits the PCB layout constraints. Ensure the operating voltage range of 2.7V to 5.5V aligns with the system power rails.

Part Context

The RT9715 series comprises single N-channel high-side power switches optimized for USB applications. These ICs are designed to provide low on-resistance and low standby current, making them suitable for portable electronics. The family includes various packages and current ratings, with the RT9715FGBR specifically utilizing the SOT-23-5R form factor.
