RT9711A/B/C/D 80mΩ Ω, 1.5A/0.6A High-Side Power Switches with Flag General Description Features The RT9711A/B/C/D are cost-effective, low voltage, single N-MOSFET high-side power switches, optimized for selfpowered and bus-powered Universal Serial Bus (USB) applications. The RT9711 series are equipped with a charge pump circuitry to drive the internal MOSFET switch. The switch's low RDS(ON), 80mΩ, meets USB voltage drop z Compliant to USB Specifications z Built-In N-MOSFET Ω (SOT-23-5 & TSOT-23-5) and ` Typical RDS(ON) : 80mΩ 90mΩ Ω (SOP-8 & MSOP-8) Output Can Be Forced Higher Than Input (Off-State) Low Supply Current : 25μ μA Typical at Switch On State 1μ μA Typical at Switch Off State Guaranteed 1.5A for RT9711A/B and 0.6A for RT9711C/D Continuous Load Current Wide Input Voltage Ranges : 2.5V to 5.5V Open-Drain Fault Flag Output Hot Plug-In Application (Soft-Start) 1.7V Typical Under-Voltage Lockout (UVLO) Current Limiting Protection Thermal Shutdown Protection Reverse Current Flow Blocking (no body diode) Smallest SOT-23-5 and TSOT-23-5 Packages Minimizes Board Space UL Approved−E219878 TUV IEC60950-1 : 2005 Certified RoHS Compliant and 100% Lead (Pb)-Free z z requirements. A flag output is available to indicate fault conditions to the local USB controller. Additional features include soft-start to limit inrush current during plug-in, thermal shutdown to prevent catastrophic switch failure from high-current loads, under-voltage lockout (UVLO) to ensure that the device remains off unless there is a valid input voltage present, fault current is limited to typically 2.5A for RT9711A/B in dual ports and 1A for RT9711C/D in single port in accordance with the USB power requirements, lower quiescent current as 25μA making this device ideal for portable battery-operated equipment. The RT9711 series are available in SOT-23-5, TSOT-23-5, SOP-8 and MSOP-8 packages fitting different aspect of broad applications.
