Power Distribution Switches, Load Drivers datasheet and documents for RT9702GB

RT9702GB

Power Distribution Switches, Load Drivers Overview

The RT9702GB is a single N-Channel MOSFET high-side power switch optimized for Universal Serial Bus (USB) applications. It features an integrated low on-resistance output, typically 80mΩ, and supports continuous load currents of up to 500mA. The device operates within a wide input voltage range from 2V to 5.5V and includes an open-drain fault flag output. Key protection mechanisms include current limiting, thermal shutdown, and reverse current flow blocking without a body diode. It utilizes a TSOT-23-5 package.
