The RT9728CHGE is a low voltage, single P-MOSFET high-side power switch IC designed for USB applications. It features a programmable current limit that can be set between 75mA and 1.3A, with a typical accuracy of ±10%. The device has a low switch-on resistance of approximately 120mΩ and a low supply current of about 120OºA. It includes a fault flag output to signal the local USB controller during fault conditions, such as over-current or reverse voltage. The RT9728CHGE also incorporates a built-in soft-start function to mitigate issues from high inrush currents. It operates within a voltage range of 2.5V to 5.5V and is available in SOT-23-6 and WDFN-6L 2x2 packages, making it suitable for various applications including USB hubs, peripheral ports, and battery-powered equipment.
