摘要
介绍了密封铅酸蓄电池充电控制器UC3906的工作原理和应用电路.UC3906包含了实现密封铅酸蓄电池最佳充电和浮充供电所需的所有的控制电路.该集成电路监控充电器的输出电压和电流,完成三种充电状态的自动转换和控制:大电流快充充电状态、可控的过充电状态和精确地浮充供电状态.由于UC3906内部的基准电压能够随密封铅酸电池的温度特性而改变,所以在很宽的温度范围内都能够保持最佳充电状态.
The operation of integrated circuit UC3906 and its application in sealed lead acid battery charger are described. The UC3906 contains all of the necessary circuitry to optimally control the boost charge and floot charge by monitoring and controlling both the output voltage and current of the charger, with which three charge modes-high current fast charge, controlled overcharge and precision float charge-will automatically and sequentially convert. Optimum charging conditions are maintained over an extended temperature range with an internal voltage reference changing with the temperature.
