说明：  UC3906作为密封铅酸蓄电池充电专用控制集成电路芯片，能够提供三种充 电逻辑状态（大电流充电、可控过充电和浮充充电）控制，能使充电器的充电 电压随电池电压温度系数的变化而变化。从而使密封铅酸蓄电池在很宽的温度 范围内达到最佳充电状态（如电池容量和使用寿命），可分别对充电电流、充 电电压（通过电压&电流控制环）实现控制，具有静态工作功耗低的优点，提 供实现密封铅酸蓄电池最佳充电所需的控制和检测功能。
(UC3906, as a special control IC chip for sealed lead-acid battery charging, can provide three charging modes Electric logic state (high current charging, controllable overcharging and floating charging) control can make the charger charging The voltage varies with the temperature coefficient of battery voltage. So that the sealed lead-acid battery at a wide temperature The best charging state (such as battery capacity and service life) can be achieved in the range of 0 The control of electric voltage (through voltage & current control loop) has the advantage of low static power consumption, so it can be used to improve the stability of the system The control and detection functions are provided for the optimal charging of sealed lead-acid batteries.)
