® RT9741 100mΩ, 1.5A/0.7A High-Side Power Switches General Description The RT9741 is a cost-effective, low-voltage, single NMOSFET high-side Power Switch IC for USB application. Low switch-on resistance (typ. 100mΩ) and low supply current (typ. 50μA) are realized in this IC. The RT9741 integrates an over-current protection circuit, a short fold back circuit, a thermal shutdown circuit and an under-voltage lockout circuit for overall protection. Furthermore, the chip also integrates an embedded delay function to prevent miss-operation from happening due to inrush-current. The RT9741 is an ideal solution for USB power supply and can support flexible applications since it is available in the SOT-23-3 package.
