Charger Evaluation Board demonstrates the features of Microchip&rsquo;s MCP73123 and MCP73223 Lithium Iron Phosphate (LiFePO4) Battery Charge Management Controller with Input Overvoltage Protection.</p> <p>The Evaluation Board is designed with two independent circuits. The MCP73123 is designed to charge a single-cell LiFePO4 battery, while the MCP73223 charges a dual-cell LiFePO4 battery. Both circuits offer two different fast charging currents. The default value of fast charging current is 500 mA and when PROG via is tie to ground, the two parallel resistors output 1000 mA fast charging current to a battery pack. One blue LED status output allows user to learn if the MCP73123/223 is in charging state or not.</p> <p>The Evaluation Board comes with installed MCP73123 and MCP73223 devices in 3mmx3mm DFN packages. The factory preset battery regulation voltage is 3.6V for the MCP73123 and 7.2V for the MCP73223 with 10% precondition current, 10% termination current set point, automatic recharge and 6.5V over voltage protection threshold voltage.</p> <p><strong>Applications:</strong> Low-Cost LiFePO4 Battery Chargers, Power Tools, Toys, Backup Energy Storage Solutions</p> </div> <h3 class="toc-item xs-pb2 xs-border-bottom">Features</h3> <ul> <li>Input Over Voltage Protection:<br /> <ul> <li>6.5V for the MCP73123</li> <li>13V for the MCP73223</li> </ul> </li> <li>Charge Regulation Voltage:<br /> <ul> <li>3.6V for the MCP73123</li> <li>7.2V for the MCP73223</li> </ul> </li> <li>10% Preconditioning of Deeply Depleted Cells</li> <li>32-Minute Preconditioning Timer</li> <li>6-Hour Safety Timer</li> <li>10% Automatic Charge Termination</li> <li>500 mA and 1000 mA Preset Fast Charge Current</li> <li>Automatic Recharge</li> <li>Thermal Regulation</li> <li>One Blue LED Charge Status Indicator For Each Circuit</li> <li>Pre-installed MCP73123 and MCP73223 Devices</li> </ul> <h3 class="toc-item xs-pb2 xs-border-bottom">Ships With</h3> <ul> <li>MCP73X23 Lithium Iron Phosphate Battery Charger Evaluation Board</li> <li>Important Information Sheet</li> </ul> <div id="devtool-required-devtools-section" class="xs-hide"> <h3 class="toc-item xs-pb2 xs-mb1 xs-border-bottom">Required Tools</h3> <div id="devtool-required-devtools-content"></div> </div> <div id="devtool-accessory-devtools-section" class="xs-hide"> <h3 class="toc-item xs-pb2 xs-mb1 xs-border-bottom">Accessory Tools</h3> <div id="devtool-accessory-devtools-content"></div> </div> <h3 class="toc-item xs-pb2 xs-border-bottom">Documents</h3> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Data Sheet</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="http://ww1.microchip.com/downloads/en/DeviceDoc/22191E.pdf" target="_blank">MCP73123/223 Data Sheet (pdf)</a> </div> </div> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Solution Guide</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="http://ww1.microchip.com/downloads/en/DeviceDoc/50001894D.pdf" target="_blank">Quick Guide to Microchip Development Tools (pdf)</a> </div> </div> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">User Manual/Guide</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="http://ww1.microchip.com/downloads/en/DeviceDoc/51850a.pdf" target="_blank">MCP73X23 OVP Lithium Iron Phosphate Battery Charger Evaluation Board User Guide (pdf)</a> </div> </div> <h3 class="toc-item xs-pb2 xs-border-bottom">Downloads</h3> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Schematics/Layout Files</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-archive"></i> <a href="http://ww1.microchip.com/downloads/en/DeviceDoc/00262R1_Gerbers.zip" target="_blank">MCP73X23EV-LFP Gerbers (zip)</a> </div> </div> </div> <div style="clear:both;"></div> <div style="font-size: 90%;">Tags: Lithium Iron Phosphate, battery charger, microchip, MCP73X23, battery_management, analog_demo_boards</div>
