STEVAL- ISB006V1演示板是基于STw4102 ，一个独立的恒流恒压（ CCCV ）线性充电器专用锂离子电池。该设备允许使用的主要输入适配器高达1A （墙上适配器，汽车适配器）或USB电缆高达500 mA无需外部元件的双充电能力。The STEVAL-ISB006V1 demonstration board is based on the STw4102, a stand-alone constantcurrent constant-voltage (CCCV) linear charger dedicated for Li-Ion battery. This device allows dual charging capability using the main input adaptor up to 1A (wall adaptor, car adaptor) or USB cable up to 500 mA without external component. Upper 1 A charging is possible by adding just one external transistor. This demonstration board offers programmable fast charge current up to 1A with external resistor. A thermal regulation circuitry limits the charge current against the die high power dissipation or high ambient temperature. An end of charge output pin indicates the charge termination when the fast charge current drops below 10% of the programmed current value. The STw4102 contains an accurate gas gauge based on a 13 bit AD converter. External resistor is used between battery and ground to sense a charge/discharge current. With a typical 30 mΩ resistor, current can be up to 2.5 A.
