Nowadays smart phone and tablet PCs all equipped with professional charger. The charger passed the test of the mobile phone or tablet PCs, also it allow the max current to charge the devices. There are four pull-down resistors, The resistors D+ and D- will detect the devices and determine the suitable current to charge. For example, if you use a Samsung charger which is 5V 1A to charge an iPhone5, the detectors D+ and D- which on the charger cannot match with the iPhone5’s,then the max charging current can only allow 500-600mA,then the charging time will be longer. But if you use the original iPhone charger, then the max current allow 960mA.That’s why we need use a smart IC chipset when we use the universal chargers.
Now Tommox R&D department opened two molds multi-USB charging center, they are our new products TX-MU600 and TX-SU700. All of them come with the smart USB IC. For example, multi-USB charging center TX-SU700 has 2 super USB charging port, which use the smart IC, can detective the devices model and choose the best current to charge it. When you use the super USB charging port to charge, it can save 80% charging time. What’s the most, it can compatible for 98% kinds 5V USB devices in the world.
