Product Overview

STCC2540IQTR is a USB charging controller with integrated power switch in a 16 pin VFQFPN package. The 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 asserts the charging flag in DCP modes if the charging current is higher than the threshold. In CDP mode, it asserts the charging flag after the CDP negotiation if the charging current is higher than the threshold. After the current drops below the threshold, the output is deasserted, allowing the host to turn off the high power DC-DC converter and reduce overall consumption in S4/S5 states, which is critical when the host is battery supplied. Typical applications include USB ports / hubs, PCs, monitors, notebooks, ultra books, tablet PCs, universal wall charging adapters.
  • Compliant with USB charging specifications BC1.2, USB 2.0 and USB 3.0 standards
  • 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 65mohm
  • Constant current mode overcurrent protection
  • Soft-start to limit inrush current
  • Adjustable current limit up to 2.8A
  • Short-circuit, thermal and undervoltage protection
  • Reverse voltage and reverse current protection
  • Deglitched fault reporting output, supports remote wakeup in S3, charging indication output
