RT9527H 是一种低成本的单节锂离子电池小电流充电器,它可从交流适配器或 USB 端口获取电源进行充电。当电源输入被移除时,RT9527H 进入睡眠状态。RT9527H 以优化的充电控制算法完成充电过程,其中包括预充电、快速充电和恒压充电三种模式。当充电完成时,它维持在恒压充电模式以确保电池总是处于充满状态。充电电流可以通过一只电阻进行调节,内部热反馈电路可对内核温度进行调节以确保在任何环境温度下都能获得最佳的充电速率。RT9527H 可以承受最高 28V 的输入电压,它还具有欠压保护和过压保护功能,其封装为 WDFN-8L 2x2。建议的接面温度范围为-40°C至125°C,而环境温度范围则为-40°C至85°C。
