淄博ASC6614升降充电管理IC方案 充电IC 完善的售后服务

ASC405允许出厂配置预充电电流/截止电流/CV 电 压和输入过压保护门限，其集成高压输入保护电路 可以承受高达 38V 的输入浪涌电压。 具有电池温度 NTC 监测、充电**时保护、输入过压、电池过压、热保护和状态指示等功能。
详情介绍：
ASC6220 为同步开关型锂离子/锂 聚合物电池充电管理芯片，非常适合于便携 式设备的充电管理应用。 ASC6220 集高精度电压和输入电流及 充电电流调节器、预充、充电状态指示和充 电截止等功能于一体，采用 TSSOP-20 或者 QFN-20 封装。 ASC6220 对电池充电分为三个阶段： 预充（ Pre-charge ）、恒流（CC/Constant Current）、恒压（CV/Constant Voltage）过程， 恒流充电电流通过外部分压电阻决定，恒压 充电电压可通过外部电阻微调。 ASC6220 集成电池温度检测，过压及 短路保护，确保充电芯片工作。 ASC6220 集成智能电池检测功能及**时错 误恢复功能，方便用户使用。
