Charge your power hungry devices from a powered down laptop
Global semiconductor leader
ST's new chips STCC5011 and STCC5021 , also called charger emulators, can detect when a mobile device is connected to the PC using ST's own patented attach-detection feature (Application number : 13904866). While other charger
As soon as they detect that a mobile device is connected, they enable the PC's power supply in order to charge the device. The chips monitor the current to turn the power supply off when the charging is complete, saving on energy.
ST claims that the chips consume only 1/16 of the power of other charger emulators allowing the PCs to charge devices with minimal impact on the PCs battery life during normal use. Provided with the circuitry to avoid discharging the PCs battery, the chips, allow mobile users to charge their devices even when using battery power alone.
Major features of STCC5011/5021:
● STCC5021 is suitable for
● Support for proprietary chargers such as Blackberry
● USB2.0, USB3.0 compatible
● Low-resistance (60mΩ) integrated power switch
● Built-in safety protection
● Charging-indication output in DCP (Dedicated Charging Port) and CDP (Charging Downstream Port) modes
