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.

Chapter 1. Product Overview

1.1 INTRODUCTION

Portable electronics has played an important role in modern era. Due to the natural characteristics of Li-Ion / Li-Polymer batteries, they are the most popular power sources for mobile devices. However, extra care in design is always important to implement Li-Ion / Li-Polymer batteries. System Power Path Management allows end-users to charge their batteries without interruption. This reference design is developed to assist product designers in reducing product design cycle and time by utilizing Microchip's favorite stand-alone Li-Ion battery charge management controllers with system power path management.

This chapter provides an overview of the Li-Ion Battery Charger System Power Path Management Reference Design and covers the following topics:

• "What is the Li-Ion Battery Charger System Power Path Management Reference Design?"
• "What the Li-Ion Battery Charger System Power Path Management Reference Design Kit includes.

FIGURE 1-1: MCP73833 With System Power Path Management Application.

1.2 WHAT IS THE LI-ION BATTERY CHARGER SYSTEM POWER PATH MANAGEMENT REFERENCE DESIGN?

The Li-Ion Battery Charger System Power Path Management Reference Design demonstrates the features of Microchip's MCP73832 "Miniature Single-Cell, Fully Integrated Li-Ion, Li-Polymer Charge Management Controllers" and MCP73833 "Miniature Single-Cell, Fully Integrated Li-Ion, Li-Polymer Charge Management Controllers" with the load sharing system power path management capability.

There are two independent circuits on the reference design. First circuit is designed with MCP73832, which allows maximum programmable fast charge current up to 500 mA. The second circuit is designed with MCP73833, which allows maximum programmable fast charge current up to 1A and has a power good indicator and an additional status output. Two preset values of fast charge current are available for each circuit by a SPDT dip on the board for users to experience different speed.

Note: Please refer to Table 2-1 for Charge Status Outputs and Table 2-2 for charge current setups.

Both circuits come with load sharing system power path management feature. This feature allows a DC Power Source to support system load while charging a Li-Ion battery. When the DC Power Source is absent, the Li-Ion battery will support system load and stop charging.

The Li-Ion Battery Charger System Power Path Management Reference Design is designed to observe the performance and features on the circuits via multiple test points. Circuits can also be implemented into suitable applications without additional work.

1.3 WHAT THE LI-ION BATTERY CHARGER SYSTEM POWER PATH MANAGEMENT REFERENCE DESIGN KIT INCLUDES

This Li-Ion Battery Charger System Power Path Management Reference Design kit includes:

• Li-Ion Battery Charger System Power Path Management Reference Design, 102-00120
• Analog and Interface Products Demonstration Boards CD-ROM (DS21912)

- Li-Ion System PPM Reference Design, DS51746

• MCP73833 Data Sheet, "Miniature Single-Cell, Fully Integrated Li-Ion, Li-Polymer Charge Management Controllers", DS21984
• MCP73832 Data Sheet, "Stand-Alone Linear Li-Ion / Li-Polymer Charge Management Controller", DS22005

Chapter 2. Installation and Operation

2.1 INTRODUCTION

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 headsets, Ultra-Mobile PC and Portable Communicators.

2.2 FEATURES

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 Li-Ion battery and system load at the same time without affecting charging algorithm of Microchip's stand-alone charge management controllers.
• The system load is supported by Li-Ion battery when input power source is removed
• Blue LED indicates charge status
• Additional Red LED to indicate Power-Good (PG) and Green LED to indicate charge complete (Available from MCP73833)
• Dip Switch to select programmable fast charge current between 1000 mA (H) and 50 mA (L) for MCP73833 and 400 mA (H) and 25 mA (L) for MCP73832
• Available THERM pin on the MCP73833 for temperature monitoring with a thermister. It is disabled by default and can be enabled to use with NTC thermister.
• Preconditioning of deeply depleted cells.
• Internal Safety Timer (available from MCP73833)
  • Automatic Charge Termination
  • Automatic Recharge
• Thermal Regulation
• Small DFN packages with Exposed Pad as additional heat sink.

2.3 GETTING STARTED

The Li-Ion Battery Charger System Power Path Management Reference Design is fully assembled and tested for charging a single-cell Li-Ion or Li-Polymer battery with or without system load.

2.3.1 Power Input and Output Connection

2.3.1.1 POWERING THE LI-ION BATTERY CHARGER SYSTEM POWER PATH MANAGEMENT REFERENCE DESIGN

1. Connect the positive battery terminal to V_BAT+ and negative battery terminal to V_BAT- .
2. Connect the 5V DC power supply Negative Terminal to V _SS .
3. Connect the 5V DC power supply Positive Terminal to V DD.
4. It should initiate the battery charging cycle when the power source is present.
5. Position the DIP Switch to "H" for 400 mA fast charge current rate of MCP73832 and 1000 mA fast charge current rate of MCP73833.
6. Position the DIP Switch to "L" for 25 mA fast charge current rate of MCP73832 and 50 mA fast charge current rate of MCP73833.

Note: Fast Charge Current can be programmed with various resistors that based on the Figure 2-1 and Figure 2-2.

Note: The Li-Ion battery pack can be replaced with test circuit or electronic load that can sink current with DC power supply. Please refer to Figure 2-3.

1. Connected positive of load to System Load on the board and negative of load to either V_SS or V_BAT- . The load can be a power resistor or E-Load.
2. Remove DC power supply, the load should be supported by the Li-Ion battery now.

Note: MCP73832 circuit is labeled "A" on the reference design while MCP73833 circuit is labeled "B" on the reference design.
