PHOENIX, Ariz. – October 18, 2016 – ON Semiconductor (Nasdaq: ON), driving energy efficiency innovations, has introduced a highly integrated single chip power bank solution for the development of next generation Li-Ion powered products. The LC709501F total Li-Ion battery solution offers broad power and voltage/current output range of 5 volt (V), 9 V and 12 V operation, with a maximum charge/discharge capability of up to 30 watts (W) through simple FET selection.
The LC709501F determines what type of device is connected and automatically selects the fastest available method for charging. Advanced users can even reprogram the LC709501F to support custom charge/discharge profiles, as well as USB Type-C and PD “Policy Engine” functions. This single-chip solution includes integrated fuel gauge function, configurable I/O, LED drivers, I2C interface, and pre-drivers for external power MOSFETs, providing system flexibility. A design reference kit is available to realize fast time to market. The LC709501F supports various output power levels up to 30 W, by changing external MOSFETs. In addition, there is an integrated USB 2.0 Full Speed host controller.
The LC709501F’s USB host controller supports connectivity with iOS and Android apps that enable 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.). The device works with the proprietary charging protocols (such as Fast Charge and Qualcomm® Quick Charge™) now being utilized by smartphone manufacturers to accelerate the charging period. To ensure operational longevity, over-current, over-voltage, and redundant battery protection mechanisms are all included, as well as a thermistor for monitoring of temperature levels. The LC709501F supports an operational temperature range of -40 °C to +85 °C.
“With a growing need for on-the-go recharging of portable electronics, power banks are certain to become more prevalent over the coming years,” states Matthew Tyler, Director Strategy and Product Roadmap Definition of the Digital and DC/DC Division at ON Semiconductor. “Accurate and reliable charge capacity indication and the ability to support the latest quick charging standards are becoming more critical, especially as power bank capacities have grown over time. The level of sophistication that power banks possess is destined to increase, so that batteries can be replenished as quickly as possible and inconvenience is minimized. The new, best-in-class LC709501F charger will enable the creation of compact, highly efficient, feature-rich power banks that will simplify and accelerate time-to-market of next generation power bank solutions. Its breadth of functionality will enhance the user experience and mean that high degrees of safety are maintained.”
Packaging and Pricing
The LC709501F is offered in a QFN-52 (6 x 6 mm) package and priced at $2.80 per unit in 10,000 unit quantities.
