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

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
