MCP73831T-2DCI/OT - IC, BATT MGMT, LI-ION/LI-POLY, SOT23-5

The MCP73831T-2DCI/OT is a miniature single-cell, fully integrated Li-ion, Li-polymer charge Management Controller for use in space limited and cost-sensitive applications. This controller employ a constant-current/constant voltage charge algorithm with selectable preconditioning and charge termination. The constant current value is set with one external resistor. This devices limit 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.
