Chapter 1. Product Overview INTRODUCTION The MCP73833 Li-Ion Battery Charger Evaluation Board is used to evaluate Microchip Technology’s MCP73833/4 in simple, stand-alone Li-Ion battery charging applications. Two circuit layouts are provided for evaluation of various device options in either the DFN or MSOP package.
In addition, the assembled MCP73833/4-FC circuit provides preconditioning of deeply depleted cells. Each board design provides evaluation of the MCP73833/4 in two package options: a MSOP-10 (not assembled) and a 3mm x 3mm, 10-Lead DFN (assembled) for higher power handling capability.
Technology’s MCP73833/4 devices. The MCP73833/4 is a Stand-Alone Linear Li-Ion/Li-Polymer Charge Management Controller. A number of device options allow the MCP73833/4 to be utilized in a variety of applications. Refer to the MCP73833/4 data sheet (DS22005) for device options. FEATURES The MCP73833 Li-Ion Battery Charger Evaluation Board contains two evaluation circuits for evaluation of various device options.
APPLYING THE LOAD TO THE MCP73833 LI-ION BATTERY CHARGER EVALUATION BOARD 1. To apply a load to the MCP73833 Li-Ion Battery Charger Evaluation Board, the positive side of the load (B+) should be connected to VBAT of the circuit being evaluated.
