INTRODUCTION
FEATURES
Chapter 2. Installation and Operation
The Li-Ion Battery Charger System Power Path Management Reference Design
demonstrates Microchip's stand-alone Linear Li-Ion Battery Chargers - MCP73832 and
MCP73833 while allowing input power source to operate the system load. The system
load can also be supported by the Li-Ion battery when input power is disconnected. A
number of device options allow the MCP73832 and the MCP73833 to be utilized in a
variety of applications. Please refer to the MCP73832 data sheet (DS21984) and
MCP73833 data sheet (DS22005) for 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 Li-Ion Battery Charger System Power Path Management Reference Design has
the following features:
• Load sharing system power path management that support charging single cell
• The system load is supported by Li-Ion battery when input power source is
