nPM2100 电源管理IC

适配一次电池、搭载高效率升压稳压器与电量计的专用 PMIC

PM2100 是一款面向一次电池应用量身打造的电源管理芯片,满足不可充电电池供电产品的专属电源管控需求。器件可适配 AA/AAA/LRxx 型碱性电池(最多两节串联)、3 伏锂锰纽扣电池(CR2032 及同规格产品)、单节 / 双节氧化银与锌空纽扣电池,以及输入电压区间 0.7~3.4 伏范围内的各类一次电池

芯片内置高效率升压稳压器并自带直通自动模式,可充分耗尽电池电量直至放电终止电压;片载 LDO 能够拓展一路独立电压电源轨。

nPM2100 集成算法型电池电量计,配套完善的系统管理功能:硬件看门狗、硬件复位、启动故障恢复、断线唤醒、运输模式与休眠模式。

Designing Low-Power Bluetooth LE Products

Designing Low-Power Bluetooth LE Products is a hands-on course focused on building Bluetooth LE products for minimal power consumption and extended battery life.

You’ll explore

  • Power budgeting
  • Power measurement tools and techniques
  • Software optimizations
  • Clock sources 
  • Power saving features
  • Power Management ICs
  • Remote monitoring with nRF Cloud

                                                             

                                                                                    

To get the most out of this course, we recommend using an nRF54L15 DK, a Power Profiler Kit II (PPK2), and an nPM2100 EK. The course also supports the nRF54LM20 DK, nRF54LS05 DK, and nRF54LV10 DK.
