RT9528 是一款经由 I<sup>2</sup>C 汇流排介面进行控制的、包含自动电源路径管理功能和 USB/AV 信号切换开关的单节锂离子电池充电 IC。它在使用时无需使用任何外置的 MOSFET ，是一款全集成化产品。在使用中，当外部电源被移除时，RT9528 自动进入睡眠模式。借助使用优化的控制逻辑，RT9528 在完成充电任务时会自动选择使用预充电模式、快充电模式和恒压充电模式，它的充电结束条件、安全计时器、充电电流和 V<sub>SYS</sub> 都可经由 I<sup>2</sup>C 控制介面进行控制。RT9528 对电池包、充电器和输入电路提供了各种保护，其中包括过流、欠压、过压、热调节和热保护。透过序列介面，充电的各种状态和故障情况都可以被监控到。在任何可用工作温度范围内，充电的速率都可通过内部温度回馈电路实现最优化的调节。</br>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。
