RichTek Technology Corporation Integrated Circuits (ICs) - Power Management (PMIC) - Power Distribution Switches, Load Drivers RT9742HGJ5

The RT9742HGJ5 is a low-voltage, single N-MOSFET high-side power switch IC designed for USB applications. It features a low switch-on resistance of 70mOc and operates within a supply voltage range of 2.7V to 6V. The device integrates several protection mechanisms, including over-current protection, short circuit protection, thermal shutdown, and under-voltage lockout, ensuring reliable operation in various conditions. Additionally, the RT9742HGJ5 includes a fault flag output to communicate fault conditions to the local USB controller and an embedded delay function to mitigate issues caused by inrush current. It is available in compact TSOT-23-5 and SOT-23-3 packages, making it suitable for space-constrained designs. This product is UL and Nemko approved, indicating compliance with safety standards.
