1 / 37 page  This is information on a product in full production. August 2014 DocID024660 Rev 6 1/37 STCC5011, STCC5021 USB charging controller with integrated power switch and attach detector Datasheet - production data Features • Compliant with USB charging specifications BC1.2, USB 2.0 and USB 3.0 standards • Compliant with Chinese telecommunications industry standard YD/T 1591-2009 • Compatible with proprietary charging mode (Apple® 1 A / 2 A, BlackBerry®, Korean tablets) • Wide bandwidth, low-loss USB 2.0 data switch • Integrated VBUS power switch with low RON of 65 m Ω • Constant current mode overcurrent protection • Soft-start to limit inrush current • Adjustable current limit up to 2.8 A • Short-circuit, thermal and undervoltage protection • Reverse voltage and reverse current protection • Deglitched fault reporting output • Supports remote wakeup in S3 • Charging indication output in DCP and CDP modes • 3-hour safety counter for charging in S5 • Device attachment detection in G3 state • Available in VFQFPN 16L 3 x 3 x 0.8 mm package with exposed pad • Temperature range: -40 up to 85 °C • UL and CB recognized components (UL file number: E354278) Applications • USB ports/hubs • Personal computers, all-in-one PCs • Monitors • Notebooks, ultrabooks • Tablet PCs • Universal wall charging adapters Description The STCC5011/STCC5021 device integrates, in one package, a USB charger controller, a wide bandwidth data switch and a high current power switch. The device emulates several profiles compatible with the USB battery charging standard BC1.2, Chinese telecommunications standard YD/T 1591-2009 and proprietary charger modes. The device can detect peripheral device attachment when the host is in S4/S5 deep sleep/off states or in G3 shutdown state. It asserts the CHARGING/ATTACH output after the attach event, allowing the host to turn on the high power DC-DC converter and start charging. This device also asserts the CHARGING/ATTACH output in DCP modes if the charging current is above the threshold. In CDP mode, it asserts the CHARGING/ATTACH output after the CDP negotiation if the charging current is above the threshold. After the current drops below the threshold, the output is deasserted. This allows the host to turn off the high power DC-DC converter and reduce overall consumption in S4/S5 or in G3 states which is critical when the host is battery-supplied. These two features permit the host system to reduce consumption while no device is attached or when there is no charging. VFQFPN 16L - 3 x 3 x 0.8 mm www.st.com |
