BC3770 Battery Charger Board with KL25Z
Manufactured By:NXP
Part Number:FRDM-BC3770-EVM
The Freedom expansion board FRDM-BC3770-EVM is a fully programmable switching charger with dual-path output for single-cell Li-Ion and Li-Polymer battery that works with a FRDM-KL25Z (included pre-programmed with mini-USB cables).
This dual-path output allows mobile applications with fully discharged battery or dead battery to boot up the system. High efficiency and switch-mode operation of the BC3770 reduces heat dissipation and allow 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 the current up to 2A. The charging parameters and operating modes are fully programmable over an I2C Interface that operates up to 400kHz.
Features
- A BC3770 highly integrated synchronous switch-mode chargers, featuring integrated OVP and Power FETs
- A FRDM-KL25Z for SPI communication and IO control
- Operate as a boost regulator for USB-OTG function via either I2C command or an external pin from the host/processor.
- The BC3770 is a fully programmable switching charger with dual-path output for single-cell Li-Ion and Li-Polymer battery. This dual-path output allows mobile applications with fully discharged battery or dead battery to boot up the system.
