説明
The MAX20361 is a fully integrated solution for harvesting energy from single-/multi-cell solar sources. The device includes an ultra-low quiescent current (360nA) boost converter that is capable of starting from input voltages as low as 225mV (typ). In order to maximize the power extracted from the source, the MAX20361 implements a proprietary maximum power point tracking (MPPT) technique that allows efficient harvesting from 15μW to over 300mW of available input power. The MAX20361 also features an integrated charging and protection circuit that is optimized for Li-ion batteries, but can also be used to charge supercapacitors, thin-film batteries, or traditional capacitors. The charger features a programmable charging cut-off voltage with thresholds programmable through I2C 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).
