INTRODUCTION
FEATURES
Chapter 2. Installation and Operation
The MCP73871 Evaluation Board demonstrates Microchip's stand-alone linear Li-Ion
battery charger with system power path and load sharing management control solution.
The system load is also supported by the Li-Ion battery when the input power is
disconnected. A number of device options allow the MCP73871 to be utilized in a
variety of applications. Refer to the MCP73871 Data Sheet (DS22090) and/or contact
local Microchip supports for additional device options.
Typical applications for the reference design are Smart Phones, PDA, Portable Media
Players, MP3 Players, Digital Cameras, Handheld Medical devices, Bluetooth head-
sets, Ultra-Mobile PC and Portable Communicators.
The MCP73871 Evaluation Board has the following features:
• Integrated System Load Sharing
