Description
The MCP73811/2 devices are linear charge manage- ment controllers that are designed for use in space limited and cost sensitive applications. The MCP73811/2 provide specific charge algorithms for single cell Li-Ion or Li-Polymer battery to achieve optimal capacity in the shortest charging time possible. Along with its small physical size, the low number of external components required make the MCP73811/2 ideally suited for portable applications. For applications charging from a USB port, the MCP73811 adheres to all the specifications governing the USB power bus. The MCP73811/2 employ a constant current/constant voltage charge algorithm. The constant voltage regula- tion is fixed at 4.20V, with a tight regulation tolerance of 1%. For the MCP73811, the constant current value is selected as 85 mA (low power USB port) or 450 mA (high power USB port) with a digital input signal on the PROG input. For the MCP73812, the constant current value is set with one external resistor. The MCP73811/2 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. The MCP73811/2 are fully specified over the ambient temperature range of -40°C to +85°C. The MCP73811/2 are available in a 5-Lead, SOT-23 package.
