nPM1300 电源管理IC

具有独特系统管理功能的电源管理集成电路(PMIC)

nPM1300 PMIC将嵌入式低功耗蓝牙设计所需的基本功能集成到小型封装中，从而简化了系统设计，可以用较少的组件实现更长的运行时间和高效的电池充电。

nPM1300经优化具有最高效率和紧凑尺寸，并可通过I2C兼容双线接口（TWI）进行配置。该接口可以方便地接入和配置一系列先进的系统管理功能，包括双按钮硬复位、电池燃料计量、系统级看门狗、断电警告和启动故障恢复。在嵌入式低功耗蓝牙设计中，这些功能通常作为分立组件来实现；然而，客户使用nPM1300可将它们集成到单一紧凑封装中，从而简化系统设计并减少所需组件数目。

nPM1300 PMIC旨在为Nordic的nRF52和nRF53系列系统级芯片（SoC）提供高效的电源调节，支持低功耗蓝牙、LE Audio、蓝牙mesh、Thread和Zigbee等无线协议。这款产品是先进的紧凑型物联网产品(先进可穿戴设备和便携式医疗应用等)的理想选择。
