♠ Stand-Alone Linear Li-Ion / Li-Polymer Charge Management Controller
The MCP73833/4 is a highly advanced linear charge management controller for use in space-limited, cost sensitive applications. The MCP73833/4 is available in a 10-Lead, 3 mm x 3 mm DFN package or a 10-Lead, MSOP package. Along with its small physical size, the low number of external components required makes the MCP73833/4 ideally suited for portable applications. For applications charging from a USB port, the MCP73833/4 can adhere to all the specifications governing the USB power bus.
The MCP73833/4 employs 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 accomodate new, emerging battery charging requirements. The constant current value is set with one external resistor. The MCP73833/ 4 limits 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 set to 100%. Refer to Section 1.0 “Electrical Characteristics” for available options and the “Product Indentification System” for standard options. The MCP73833/4 is fully specified over the ambient temperature range of -40°C to +85°C.
