element14 has announced the Freescale BC3770 Battery Charger Evaluation kit geared for engineers designing mobile devices that require Li-ion or LiPo battery charging. It is aimed at users wanting to develop a charger that can charge the battery, as well as power the device with a drained battery at the same time.

The Freescale FRDM-BC3770-EVM is a low cost, fully programmed development tool that shows designers how to implement a dual-path lithium battery charger. Priced at about $53 and available for next day delivery, the kit comes with two boards the FRDM-BC3770 board with a pre-programmed FRDM-KL25Z that operates the FRDM-DC3770 battery charger.

Designed to charge Li-ion or LiPo batteries for mobile applications, the kit has a complete graphical user interface for setting parameters and monitoring charging performance. Battery operated consumer or industrial portable devices such as mobile phone chargers, POS or rechargeable medical devices or tablets are just a few of the target applications.

The FRDM-BC3770-EVM is a pre-programmed/ fully programmable switching charger with dual-path output for single-cell Li-ion and Li-polymer batteries. High efficiency and switch-mode operation of the BC3770 reduces heat dissipation and allows for higher current capability for a given package size. In addition, the BC3770 features single input with a 20V max input and charges the battery with a current up to 2A. The charging parameters and operating modes are fully programmable over an I2C Interface that operates up to 400kHz.

The Freescale BC3770 battery charger evaluation kit is available from Farnell element14 in Europe, Newark element14 in North America and element14 in Asia Pacific.
