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