RT9711A/B/C/D 1 DS9711A/B/C/D-03 April 2011 www.richtek.com 80mΩ, 1.5A/0.6A High-Side Power Switches with Flag Marking Information For marking information, contact our sales representative directly or through a Richtek distributor located in your area. General Description The RT9711A/B/C/D are cost-effective, low voltage, single N-MOSFET high-side power switches, optimized for self- powered 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 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. Features Compliant to USB Specifications Built-In N-MOSFET Typical RDS(ON) : 80mΩ (SOT-23-5 & TSOT-23-5) and 90mΩ (SOP-8 & MSOP-8) Output Can Be Forced Higher Than Input (Off-State) Low Supply Current : 25μA Typical at Switch On State 1μA 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 Applications USB Bus/Self Powered Hubs USB Peripherals ACPI Power Distribution PC Card Hot Swap Notebook, Motherboard PCs Battery-Powered Equipment Hot-Plug Power Supplies Battery-Charger Circuits Note : Richtek products are : RoHS compliant and compatible with the current require- ments of IPC/JEDEC J-STD-020.

Stresses listed as the above "Absolute Maximum Ratings" may cause permanent damage to the device. These are for stress ratings. Functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may remain possibility to affect device reliability. Note 2. θJA is measured in the natural convection at TA = 25°C on a low effective thermal conductivity single layer test board of JEDEC 51-3 thermal measurement standard. Note 3. Devices are ESD sensitive. Handling precaution is recommended. Note 4. The device is not guaranteed to function outside its operating conditions. Note 5. The FLAG delay time is input voltage dependent, see“ Typical Operating Characteristics” graph for further details.
