Single Cell Lithium-Ion Charge Management Controller

Description

The MCP73828 is a battery charger controller for single cell Lithium-Ion (Li-Ion) batteries. Using an external PMOS transistor, safe and fast charging of a single Li-Ion cell is accomplished. Features include, over-current foldback, charge complete output, and continuous temperature monitor. An overall system accuracy of 1% ensures that the cell capacity is fully utilized without cycle life degradation. An external resistor can set charge current. The MCP73828 operates with an input voltage range from 4.5V to 5.5V. It is specified over the ambient operating temperature range of -20°C to +85°C and is available in a small 8-Pin MSOP.
