Battery-charger evaluation kit for consumer or industrial devices

Aimed at engineers designing mobile devices that require Li-ion or LiPo battery charging, the Freescale BC3770 Battery Charger Evaluation Kit is now available from Farnell element14. 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. It 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. Typical target applications include battery-operated consumer or industrial portable devices such as mobile phone chargers, POS or rechargeable medical devices or tablets. 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.
