RT9715BGQW

Overview

The RT9715BGQW is a single N-channel high-side power switch IC designed for USB applications. It features a typical on-resistance of 90mΩ and supports an operating voltage range of 2.7V to 5.5V. The device integrates fixed over-current protection, thermal shutdown with foldback, reverse current blocking, and under-voltage lockout. It includes a deglitched fault flag output and operates within a junction temperature range of -40°C to 100°C. The component is housed in a 6-lead WDFN (2x2) package.

Feature Summary

• Integrates a low on-resistance N-MOSFET switch for efficient power delivery
• Provides comprehensive fault protection including over-current, thermal shutdown, and reverse current blocking
• Outputs a deglitched status flag to indicate fault conditions

Applications

• USB peripheral devices
• Notebook PC power distribution
