Note the following details of the code protection feature on Microchip devices:

• Microchip products meet the specification contained in their particular Microchip Data Sheet.

• Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the

intended manner and under normal conditions.

• There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our

knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data

Sheets. Most likely, the person doing so is engaged in theft of intellectual property.

• Microchip is willing to work with the customer who is concerned about the integrity of their code.

• Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not

mean that we are guaranteeing the product as “unbreakable.”

Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our

products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts

allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

USER’S GUIDE

Chapter 1. Product Overview

1.1 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 (RPROG) 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.”

1.2 WHAT IS THE MCP73830L 2X2 TDFN LI-ION BATTERY CHARGER

EVALUATION BOARD?

The MCP73830L 2x2 TDFN Li-Ion Battery Charger Evaluation Board demonstrates the

use of Single-Chip Linear Li-Ion Battery Charger with programmable charge current.

The MCP73830L 2x2 TDFN Li-Ion Battery Charger Evaluation Board is set up to

evaluate single-cell Li-Ion battery charge management. This board utilizes Microchip's

MCP73830L thateffectively chargesLi-Ion batteries withhigh-accuracy,preset-voltage

regulation. The MCP73830L 2x2 TDFN Li-Ion Battery Charger Evaluation Board

comes with a pre-installed 2 mm x 2 mm TDFN-6 MCP73830L. This circuit is ready to

charge Li-Ion batteries at a maximum charge current rate up to 200 mA.

A built-in LED is used to display the charge status (STAT).

The MCP73830L has an internal safety timer and will terminate the charge cycle when

the timer has expired.

The MCP73830L 2x2 TDFN Li-Ion Battery Charger Evaluation Board is designed to

observe the performance and features on the circuits via multiple test points. Users can

also discover the compact size of the layout in addition to the device itself. The circuit

can also be implemented into suitable applications without additional work.

1.3 WHAT THE MCP73830L 2X2 TDFN LI-ION BATTERY CHARGER

EVALUATION BOARD KIT INCLUDES

This MCP73830L 2x2 TDFN Li-Ion Battery Charger Evaluation Board kit includes:
