STCC5021：USB charging controller with integrated power switch and attach detection
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/ATTACHoutput 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/ATTACHoutput in DCP modes if the charging current is above the threshold. In CDP mode, it asserts the CHARGING/ATTACHoutput 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.
