Silabs公司的EFP01是能量友好功率管理集成电路(PMIC),具有极好的灵机一动,高效率,多输出功率管理集成电路,为EFM32和EFR32器件提供完整的系统功率和原电池库仑计数.EFP01工作在宽输入电压(0.8V到5.5V),静态电流低至300nA(EM2模式,单输出使能).EFP01支持下面的电池类型:1) 单个碱性锌锰电池(Zn/MnO2),碳锌电池, 锂/二硫化铁(Li/FeS2)原电池,或NiMH/NiCd可充电电池(0.8V-1.8V).2) 双碱性, 碳锌电池或锂/二硫化铁(Li/FeS2)原电池,或NiMH/NiCd可充电电池(1.6V-3.6V) .3) 单个锂(Li/MnO2)原电池(1.8V-3.2V), 4)单个锂亚硫酰氯(Li/SOCl2)原电池(3.0V-3.65V),5)单个锂离子聚合物(典型LiCoO2)可充电电池(2.7V-4.35V),6)单个磷酸亚铁锂电池(LiFePO4)可充电电池(2.5V-3.65V),以及USB(<5.5V).EFP01能量友好特性包括提供4个电源输出:一个降压/升压DC/DC转换器,一个仅为降压DC/DC转换器+LDO,一个LDO,一个开关输出.效率高达94%.器件工作温度-40 到100 °C ,采用QFN20 3x3 mm封装.主要用在案IoT传感器和终端设备,计量,家庭和建筑物自动化与安全,健康和健美,可穿戴,智能附件以及人机接口设备.本文介绍了EFP0101GM20能量友好特性和主要特性,框图和降压/升压配置图, 有线升压配置图, 升压前端框架配置图以及评估板BRD8100B主要特性,框图和系列产品硬件参考设计电路图.

The EFP01 Energy Friendly Power Management IC (PMIC) is anextremely flexible, highly efficient, multi-output power managementIC, providing complete system power and primary cell battery Coulombcounting for EFM32 and EFR32 devices. The EFP01 can operateover a wide input voltage range (0.8 to 5.5 V) with quiescentcurrent as low as 300 nA (EM2 mode, single output enabled).

EFP01 can be configured to support the following battery types:

• Single alkaline (Zn/MnO2), zinc-carbon or lithium iron-disulfide (Li/FeS2) primary cells,or NiMH/NiCd rechargeable cells (0.8 to 1.8 V)

• Dual alkaline, zinc-carbon or lithium iron-disulfide (Li/FeS2) primary cells, or NiMH/NiCd rechargeable cells (1.6 to 3.6 V)

• Single lithium (Li/MnO2) primary cells (1.8 to 3.2 V)

• Single lithium thionyl chloride (Li/SOCl2) primary cell (3.0 to 3.65 V)
