APPLICATION NOTE 3841
Improving Accuracy of the MAX1737 Lithium-Ion Battery Charger

Abstract: This application note describes how to improve full-scale current-sense and charge-termination
accuracy of the MAX1737 lithium-ion (Li+) battery charger. The MAX1737 current-sense is more accurate than
stated in the data sheet, but different calculations are needed to realize the improvement. Examples are
shown in the article.


Introduction

The current-sense on the MAX1737 is more accurate than stated in the data sheet. The data-sheet limits
represent 6-sigma numbers and are very conservative. Sample test data suggests approximately a 4-sigm……
