Overview

19-2099; Rev 0; 7/01 ILABLE N KIT AVA EVALUATIO Simple Current-Limited Switch-Mode Li+ Charger Controller General Description The low-cost MAX1873R/S/T provides all functions needed to simply and efficiently charge 2-, 3-, or 4series lithium-ion cells at up to 4A or more.
It provides a regulated charging current and voltage with less than ±0.
75% total voltage error at the battery terminals.
An external P-channel MOSFET operates in a step-down DC-DC configuration to efficiently charge batteries in low-cost designs.
The MAX1873R/S/T regulates the battery voltage and charging current using two control loops that work together to transition smoothly between voltage and current regulation.
