MAX20361 Small, Single-/Multi-Cell Solar Harvester with MPPT and Harvest Counter General Description Benefits and Features The MAX20361 is a fully integrated solution for Single-/Multi-Cell Solar Energy Harvester harvesting energy from single-/multi-cell solar sources. 225mV to 2.5V (typ) Input-Voltage Range The device includes an ultra-low quiescent current Efficient Harvesting from 15W to Over 300mW (360nA) boost converter that is capable of starting from of Available Input Power input voltages as low as 225mV (typ). In order to - 86% Efficiency at V = 3.8V, I = 30mA SYS SRC maximize the power extracted from the source, the Small Solution Size MAX20361 implements a proprietary maximum power - Utilizes Small 2016 4.7H Inductor point tracking (MPPT) technique that allows efficient Maximum Power Point Tracking (MPPT) Technique harvesting from 15W to over 300mW of available input Using Fractional VOC Method power. Programmable Fractional VOC Regulation Point The MAX20361 also features an integrated charging 2 through I C Interface and protection circuit that is optimized for Li-ion Battery/Supercapacitor Charger batteries, but can also be used to charge Programmable Battery Termination Voltage supercapacitors, thin-film batteries, or traditional 2 through I C Interface capacitors. The charger features a programmable Programmable Power Good Wake-Up Signal charging cut-off voltage with thresholds programmable 2 Output Threshold through I C Interface 2 through I C interface as well as temperature shutoff. The MAX20361 is available in a 12-bump, 0.4mm pitch, 1.63mm x 1.23mm wafer-level package (WLP). Ordering Information at end of data sheet.
