TI produces a small chip to the wireless recharging

Texas Instruments has designed a new chip for charging wireless receiver characterized by very contained dimensions. The model bq51013 measures just 3mm on its longest side and is able to provide a power of 5W for inductive charging smartphones, MP3 players and other mobile devices. The chip is compatible with the systems that support the standard power Qi, offers a maximum efficiency of 93 percent and causes the device to recharge as fast as a conventional charger wire.


Currently, the wireless charging technology, although very interesting, has not found a widespread use. Palm was one of the first manufacturers to adopt it through an optional package for the Pre and since acquired by HP for the TouchPad. Other producers are trying to push the technology, but thanks to the newness of IT that allows easy integration with a low cost, the process could be accelerated.
