The BC3770 battery charger evaluation kit from Freescale which is aimed at engineers designing mobile devices that require Li-ion or LiPo battery charging is available at element14. The 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 £34.93 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.

It is ideal for users wanting to develop a charger that can not only charge the battery but can also power the device with a drained battery at the same time.

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.
