Single chip power bank charging IC supports custom charge/discharge profiles

The power banks are becoming popular so that people can charge their mobile phone anywhere they are. To make the power bank design simpler, ON Semiconductor is offering a single chip IC for power bank charging. The LC709501F basically finds out what is the type of device connected to it automatically and select the best and fast available method for charging the power bank. The LC709501F supports Li-Ion battery with wide power voltage and current range of 5 volt (V), 9 V and 12 V operations and a maximum charge/discharge capability of up to 30 watts (W) through simple FET selection. This IC chip can be programmed to support custom charge/discharge profiles and even USB Type-C and PD Policy Engine functions. The other functions integrated in this device include fuel gauge function, configurable I/O, LED drivers, I2C interface, and pre-drivers for external power MOSFETs. A design reference kit is also made available to quickly design to test this particular IC. Integrated USB 2.0 Full Speed host controller is also made available. The LC709501F’s USB host controller supports connectivity with iOS and Android apps that supports the device to communicate with the connected Smartphone and subsequently make use of its display to show information concerning the battery health and the charging process (charging time, battery life, number of charging cycles completed, etc.).
