INTRODUCTION

The MCP73830L 2x2 TDFN Li-Ion Battery Charger Evaluation Board demonstrates the 
features and abilities of Microchip’s MCP73830L Single-Chip Linear Li-Ion Battery 
Charger. The MCP73830L is a stand-alone, highly integrated linear battery charge 
management controller that employs a constant current / constant voltage (CCCV) 
charge algorithm with selectable preconditioning and charge termination. The charge 
algorithm is provided for Li-Ion / Li-Polymer battery packs to achieve optimal capacity 
in the shortest charging time possible.

The MCP73830L uses an external resistor (R

PROG

) to set the magnitude of the charge 

current up to a maximum of 200 mA.

This chapter covers the following topics:

• “What is the MCP73830L 2x2 TDFN Li-Ion Battery Charger Evaluation Board?”

• “What the MCP73830L 2x2 TDFN Li-Ion Battery Charger Evaluation Board Kit 

Includes.”
