  • MCP73831 IC - (SMD SOT-23 Package) - Li-ion Battery Charger IC

The MCP73831 devices are highly advanced linear charge management controllers for use in spacelimited, cost-sensitive applications. The MCP73831 are available in an 8-Lead, 2 mm x 3 mm DFN package or a 5-Lead, SOT-23 package. Along with their small physical size, the low number of external components required make the MCP73831 ideally suited for portable applications. For applications charging from a USB port, the MCP73831 adhere to all the specifications governing the USB power bus. The MCP73831 employ a constant-current/constant voltage charge algorithm with selectable preconditioning and charge termination. The constant voltage regulation is fixed with four available options: 4.20V, 4.35V, 4.40V or 4.50V, to accommodate new, emerging battery charging requirements. The constant current value is set with one external resistor. The MCP73831 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. Several options are available for the preconditioning threshold, preconditioning current value, charge termination value and automatic recharge threshold. The preconditioning value and charge termination value are set as a ratio or percentage of the programmed constant current value. Preconditioning can be disabled The MCP73831 devices are fully specified over the ambient temperature range of -40°C to +85°C.
