EFP0109GM20-DR

Energy friendly power management IC (PMIC) is an extremely flexible, highly efficient, multi-output power management IC providing complete system power and primary cell battery Coulomb counting for EFM32 and EFR32 devices. EFP01 can be configured to support the following battery types such as single alkaline (Zn/MnO2), zinc-carbon or lithium iron-disulfide (Li/FeS2) primary cells or NiMH/NiCd rechargeable cells (0.8 to 1.8V), dual alkaline, zinc-carbon or lithium iron-disulfide (Li/FeS2) primary cells, or NiMH/ NiCd rechargeable cells (1.6 to 3.6V), single lithium (Li/MnO2) primary cells (1.8 to 3.2V), single lithium thionyl chloride (Li/SOCl2) primary cell (3.0 to 3.65V), single lithium ion/lithium polymer (typically LiCoO2) rechargeable batteries (2.7 to 4.35V) and USB (<lt/> 5.5V). EFP01 applications include the following namely IoT sensors and end devices, metering, home and building automation and security, health and wellness, wearables, smart accessories, human interface devices.
