MCP73831/2 Miniature Single-Cell, Fully Integrated Li-Ion, Li-Polymer Charge Management Controllers Features: Description: Linear Charge Management Controller: The MCP73831/2 devices are highly advanced linear charge management controllers for use in space- - Integrated Pass Transistor limited, cost-sensitive applications. The MCP73831/2 - Integrated Current Sense are available in an 8-Lead, 2 mm x 3 mm DFN package - Reverse Discharge Protection or a 5-Lead, SOT-23 package. Along with their small High Accuracy Preset Voltage Regulation: + 0.75% physical size, the low number of external components Four Voltage Regulation Options: required make the MCP73831/2 ideally suited for portable applications. For applications charging from a - 4.20V, 4.35V, 4.40V, 4.50V USB port, the MCP73831/2 adhere to all the Programmable Charge Current: 15 mA to 500 mA specifications governing the USB power bus. Selectable Preconditioning: The MCP73831/2 employ a constant-current/constant- - 10%, 20%, 40%, or Disable voltage charge algorithm with selectable Selectable End-of-Charge Control: preconditioning and charge termination. The constant - 5%, 7.5%, 10%, or 20% voltage regulation is fixed with four available options: Charge Status Output 4.20V, 4.35V, 4.40V or 4.50V, to accommodate new, - Tri-State Output - MCP73831 emerging battery charging requirements. The constant current value is set with one external resistor. The - Open-Drain Output - MCP73832 MCP73831/2 devices limit the charge current based on Automatic Power-Down die temperature during high power or high ambient Thermal Regulation conditions. This thermal regulation optimizes the Temperature Range: -40C to +85C charge cycle time while maintaining device reliability. Packaging: Several options are available for the preconditioning - 8-Lead, 2 mm x 3 mm DFN threshold, preconditioning current value, charge - 5-Lead, SOT-23 termination value and automatic recharge threshold. The preconditioning value and charge termination Applications: value are set as a ratio or percentage of the programmed constant current value. Preconditioning Lithium-Ion/Lithium-Polymer Battery Chargers can be disabled. Refer to Section1.0 Electrical Personal Data Assistants Characteristics for available options and the Cellular Telephones Product Identification System for standard options. Digital Cameras The MCP73831/2 devices are fully specified over the MP3 Players ambient temperature range of -40C to +85C.
