Products Detail

The RT9742 is a cost-effective, low-voltage, single N-MOSFET high-side power switch IC designed for USB applications. It features low switch-on resistance (70mΩ/55mΩ typical) and low supply current. The device integrates comprehensive protection circuits including over-current protection, short fold-back circuit, thermal shutdown, and under-voltage lockout. A flag output indicates fault conditions to the local USB controller, and an embedded delay function prevents miss-operation due to inrush current. Available in TSOT-23-5, TSOT-23-5 (FC), and SOT-23-3 packages, it supports flexible USB power supply applications.
