LC709501F is a highly integrated new single-chip mobile power solution from ON Semiconductor for the development of next-generation lithium-ion power products.
The entire Li-ion battery solution provides wide power and voltage / current output ranges of 5V, 9V and 12V. With simple FET selection, the maximum charge / discharge capacity is up to 30W.
The LC709501F determines the type of device connected and automatically selects the fastest available charging method. Advanced users can even reprogram the LC709501F to support custom charge / discharge profiles and USB Type-C and PD'Policy Engine features. This single-chip solution includes integrated fuel gauge functions, configurable I / O, LED drivers, I2C interfaces, and pre-drivers for external power MOSFETs, providing system flexibility.
Design reference kits are available for quick time to market. By replacing the external MOSFET, the LC709501F can support various output powers up to 30W. In addition, there is an integrated USB 2.0 full-speed host controller.
The LC709501F's USB host controller supports connections to iOS and Android applications, enabling the device to communicate with connected smartphones, and then using its display to display information about battery health and charging process (charging time, battery life , Charging times) cycle completed, etc.). The device can be used with proprietary charging protocols now used by smartphone manufacturers, such as fast charging and Qualcomm fast charging, to speed up charging time. To ensure longevity, including overcurrent, overvoltage and redundant battery protection mechanisms, and thermistors for monitoring temperature levels. The company states that the LC709501F supports an operating temperature range of -40C to + 85C and is available in a QFN-52 (6mm x 6mm) package.
"As the demand for mobile charging for portable electronics continues to grow, mobile power is sure to become more and more popular in the next few years," said Matthew Tyler, Strategy Director and Product Roadmap Definition Manager, Digital and DC-DC Division of ON Semiconductor Say. . "Accurate and reliable charging capacity indications and the ability to support the latest fast charging standards are becoming increasingly important, especially as the capacity of mobile power sources continues to grow. The complexity of mobile power sources is destined to increase so that batteries can be replenished as soon as possible, And minimize the inconvenience. The new best-in-class LC709501F charger will be able to create a compact, efficient and feature-rich mobile power supply, thereby simplifying and accelerating the time to market for the next generation of mobile power solutions.
