STEVAL-ISB002V1是一种基于ST72F324L微控制器的通用电池充电器(UBC)的演示板。该演示板可充电单节锂离子电池,内置NTC或从5 V电源2节镍氢电池。固件很容易升级,并且可以修改根据应用需求等ST7微控制器。The STEVAL-ISB002V1 is a universal battery charger (UBC) demonstration board based on the ST72F324L microcontroller.The charger used in this demonstration board uses a modified form of a non-inverting buckboost converter to support the charging voltage requirement for single-cell Li-ion batteries.The board includes a 3.3 V power supply generated from a KF33 regulator and a precision reference voltage generated from the TL1431, bearing in mind the accuracy requirement for charging. A status LED is used to show the charging status.This demonstration board is capable of charging single cell Li-ion batteries with in-built NTC or a 2-cell NiMH battery from a 5 V supply. The firmware is easily upgradeable and can be modified for other ST7 microcontrollers depending on application requirements.
