The 10AEM10330J0000 from e-peas is a Buck-Boost Energy Manager that is designed to extract DC power from ambient energy sources enabling simultaneous power supply to applications while storing excess energy in storage elements. It requires an input voltage of 0.275-4.5 V. This power management IC (PMIC) employs open-circuit voltage sensing for Maximum Power Point Tracking (MPPT). It integrates an ultra-low power DC-DC converter that operates with input voltages ranging from 100 mV to 4.5 V. This PMIC allows automatic switching between boost, buck-boost, and buck operations. It supports fast supercapacitor charging and incorporates a dual-cell supercapacitor balancing circuit. It offers selectable over-charge and over-discharge protection suitable for various rechargeable batteries or supercapacitors. This PMIC is available in a surface-mount package that measures 5 x 5 mm and is suitable for asset tracking/monitoring, retail ESL/smart sensors, aftermarket automotive, smart home/building, and industrial applications.
