® RT9742 Ω, 3A/2.5A/2A/1.5A/1A/0.5A High-Side Power 70mΩ Ω/55mΩ Switches with Flag General Description Features The RT9742 is a cost-effective, low-voltage, single N-MOSFET high-side Power Switch IC for USB application. Low switch-on resistance and low supply current are realized in this IC.      The RT9742 integrates an over-current protection circuit, a short fold back circuit, a thermal shutdown circuit and an under-voltage lockout circuit for overall protection. Besides, a flag output is available to indicate fault conditions to the local USB controller. Furthermore, the chip also integrates an embedded delay function to prevent miss-operation from happening due to inrush-current. The RT9742 is an ideal solution for USB power supply and can support flexible applications since it is available in TSOT-23-5, TSOT-23-5 (FC) and SOT-23-3 package.      Ω (typ.)
