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。

nPM1300 EK

The nPM1300 Evaluation Kit is the go-to development hardware for the nPM1300 PMIC. It integrates seamlessly with nPM PowerUP, a desktop app for code-free evaluation and development with the nPM1300.

nPM Fuel Gauge board

The nPM Fuel Gauge board (nPM FG) connects to the nPM1300 Evaluation Kit and is used for profiling batteries for use with the Nordic Fuel Gauge.
