MCP73830/L Single-Cell Li-Ion/Li-Polymer Battery Charge Management Controllers Overview

The MCP73830/L are highly integrated, Li-Ion battery charge management controllers for use in space-limited applications. The MCP73830/L devices provide specific charge algorithms for single-cell 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 MCP73830/L ideally suitable for portable applications.

The main features of the MCP73830/L include:

• Constant-Current/Constant-Voltage Operation
• Soft-Start to Avoid Inrush Current
• High-Accuracy Preset Voltage Regulation
• Preconditioning (10% and no preconditioning)
• Programmable Charge Current: 20 mA to 200 mA (MCP73830L) or 100 mA to 1000 mA (MCP73830)
• Complete Linear Charge Management Controller – Integrated pass transistor, current sense, reverse discharge protection
• Fixed Preconditioning Timer: 1 Hour
• Fixed Elapsed Timer: 4 Hours
• Automatic End-of-Charge (EOC) Control Termination (7.5% and 10%)
• Automatic Power-Down when Input Power Removed
• Automatic Recharge: No Auto-Recharge is also available
