MCP73827中文资料Single Cell Lithium-Ion Charge Management Controller数据手册Microchip规格书

描述 Description

The MCP73827 is a battery charger controller for single cell 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 current monitor, and charge status LED indicator output. An overall system accuracy of 1% ensures that the cell capacity is fully utilized without cycle life degradation. An external resistor sets charge current. The MCP73827 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 space-saving 8-Pin MSOP.
