STCC5011 and STCC5021

Originally designed for PC, the new STCC5011 and STCC5021 open new USB charging possibilities to other applications.

Applications:

Car infotainment
Cradles & docking stations
Home audio systems
Set Top Boxes

Thanks to these new ICs, any USB Host can emulate the behavior of a charger, compatible with the largest choice of brands and all kind of mobile devices such as smart phones, media players, personal navigation devices or tablets.

STCC5011 and STCC5021 have built-in a full set of protections: adjustable current limit up to 2.5A, thermal shutdown, 3h timeout, under-voltage, reverse voltage and reverse current protection. They also reach unique performances allowing users to charge mobile devices from a USB port even when the system is in shutdown mode. Using a unique attach-detection feature, which is patented by ST, it can detect when a mobile device has been connected or disconnected. This enables the system’s power supply to be activated for charging and disabled when charging is complete and thereby maximize the energy savings.

ST’s chips consume only 1/16 of the power of other charger emulators. This allows minimal impact on power consumption or battery life during normal use.
Both chips are compatible with the USB battery charging standard BC1.2, USB2.0, USB3.0, and Chinese telecommunications standard YD/T 1591-2009, which mandates use of USB charging to reduce electronic waste and protect the environment.

Major features of STCC5011/5021:

Low power attach detection mode (typ. 13µA)
Adjustable current limit up to 2.5A
Pin-selectable charger-emulation profiles
USB2.0-compliant USB data switch with 1000MHz bandwidth
Low-resistance (60mΩ) integrated power switch
Built-in safety protection
Charging-indication output in DCP (Dedicated Charging Port) and CDP (Charging Downstream Port) modes
VFQFPN 16-pin 3 x 3 x 0.8mm package
