Kit Overview

The MCP73113MCP73113 OVP Single-Cell Li-Ion Battery Charger Evaluation Board (MCP73113EV-1SOVPMCP73113EV-1SOVP) demonstrates the features of Microchip’s MCP73113 “Single-Cell Li-Ion / Li-Polymer Battery Charge Management Controller with Input Overvoltage Protection”.

The MCP73113MCP73113 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.

The MCP73113MCP73113 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.

The MCP73113MCP73113 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.

The MCP73113MCP73113 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.

Key Applications: Low-Cost Li-Ion/Li-Poly Battery Chargers, MP3 Players, Digital Still Camera, Portable Media Players, Handheld Devices, Bluetooth Headsets, USB Chargers
