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.”

Chapter 1. Product Overview

1.1 INTRODUCTION

The MCP73113 product family is highly integrated linear charge management controllers for single-cell Li-Ion and Li-Polymer batteries. The MCP73113 product family operates with minimum external components, which is ideal for use in space-limited and cost-effective applications. The input over voltage protection and battery short circuit protection offer designers a secondary protection in addition to the Li-Ion battery protection circuit.

This chapter provides an overview of the MCP73113 OVP Single-Cell Li-Ion Battery Charger Evaluation Board and covers the following topics:

• "What is the MCP73113 OVP Single-Cell Li-Ion Battery Charger Evaluation Board?"
• "What the MCP73113 OVP Single-Cell Li-Ion Battery Charger Evaluation Board Kit includes:"

1.2 WHAT IS THE MCP73113 OVP SINGLE-CELL LI-ION BATTERY CHARGER EVALUATION BOARD?

The MCP73113 OVP Single-Cell Li-Ion Battery Charger Evaluation Board demonstrates the features of Microchip's MCP73113 "Single-Cell Li-Ion / Li-Polymer Battery Charge Management Controller with Input Overvoltage Protection".

The MCP73113 OVP Single-Cell Li-Ion Battery Charger Evaluation Board is designed with two charging current. The default value is 500 mA and when PROG via is tied to ground, the two parallel resistors output 1000 mA charging current to a Li-Ion battery. One blue LED status output allows the user to learn if the MCP73113 is in charging state or not.

Note: Please refer to Table 2-1 for Charge Status Outputs and Table 2-2 for Charge Current Setups.

The MCP73113 OVP Single-Cell Li-Ion Battery Charger Evaluation Board comes with an installed MCP73113 device in 3mm x 3mm DFN package. The factory preset battery regulation voltage is 4.20V with precondition, termination and auto recharge features.

The MCP73113 OVP Single-Cell Li-Ion Battery Charger Evaluation Board 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.

Chapter 2. Installation and Operation

2.1 INTRODUCTION

The MCP73113 is a highly integrated Li-Ion battery charge management controller for use in space-limited and cost-sensitive applications. The MCP73113 provides specific charge algorithms for Li-Ion / Li-Polymer batteries to achieve optimal capacity and safety in the shortest charging time possible. Along with its small physical size, the low number of external components makes the MCP73113 ideally suitable for portable applications.

The absolute maximum voltage, up to 18V, allows the use of MCP73113 in harsh environments, such as low cost wall wart.

The MCP73113 employs a constant current / constant voltage charge algorithm. The various charging voltage regulations provide design engineers flexibility to use in different applications. The fast charge, constant current value is set with one external resistor from 130 mA to 1100 mA. The MCP73113 limits the charge current based on die temperature during high power or high ambient conditions. This thermal regulation optimizes the charge cycle time while maintaining device reliability.

The PROG pin of the MCP73113 also serves as enable pin. When high impedance is applied, the MCP73113 will be in standby mode.

Typical applications for the reference design are Smart Phones, PDA, Portable Media Players, MP3 Players, Digital Cameras, Handheld Medical devices, Bluetooth headsets and Portable Communicators.

2.2 FEATURES

The MCP73113 OVP Single-Cell Li-Ion Battery Charger Evaluation Board has the following features:

• 6.5V Input Over Voltage Protection
• 10% Preconditioning of deeply depleted cells
• 32-Minute Preconditioning Timer
- 6-Hour Safety Timer
• 10% Automatic Charge Termination
- 500 mA and 1000 mA Preset Fast Charge Current
• Automatic Recharge
- Thermal Regulation
• One Blue LED indicates charge status
- Small DFN packages with Exposed Pad as additional heat sink

2.3 GETTING STARTED

The MCP73113 OVP Single-Cell Li-Ion Battery Charger Evaluation Board is fully assembled and tested for charging a single-cell Li-Ion or Li-Polymer battery.

2.3.1 Power Input and Output Connection

2.3.1.1 POWERING THE MCP73113 OVP SINGLE-CELL LI-ION BATTERY CHARGER EVALUATION BOARD

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 and V_BAT is below recharge threshold. For example, when V_REG is 4.2V, V_BAT needs to be lower than 3.99V to initiate the charge cycle.

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

1. The charging status table is available in Table 2-2.
2. The fast charge current is preset at 500 mA and can be increased to 1A by connecting PROG via to ground.

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