MCP73213 Dual-Cell Li-Ion/Li-Polymer Battery Charge Management Controller with Input Overvoltage Protection Features Description Complete Linear Charge Management Controller: The MCP73213 is a highly integrated Li-Ion battery charge management controller for use in space-limited - Integrated Input Overvoltage Protection and cost-sensitive applications. The MCP73213 - Integrated Pass Transistor provides specific charge algorithms for dual-cell Li-Ion/ - Integrated Current Sense Li-Polymer batteries to achieve optimal capacity and - Integrated Reverse Discharge Protection safety in the shortest charging time possible. Along Constant Current/Constant Voltage Operation with its small physical size, the low number of external with Thermal Regulation components makes the MCP73213 ideally suitable for portable applications. The absolute maximum voltage, 4.15V Undervoltage Lockout (UVLO) up to 18V, allows the use of MCP73213 in harsh 13V Input Overvoltage Protection environments, such as low-cost wall wart or voltage High Accuracy Preset Voltage Regulation through spikes from plug/unplug. Full Temperature Range (-5C to +55C 0.6%) The MCP73213 employs a constant current/constant Battery Charge Voltage Options: voltage charge algorithm. The various charging voltage - 8.20V, 8.40V, 8.7V or 8.8V regulations provide design engineers flexibility to use in Resistor Programmable Fast Charge Current: different applications. The fast charge, constant current - 130 mA-1100 mA value is set with one external resistor from 130 mA to 1100 mA. The MCP73213 limits the charge current Preconditioning of Deeply Depleted Cells: based on die temperature during high-power or high- - Available Options: 10% or Disable ambient conditions. This thermal regulation optimizes Integrated Precondition Timer: the charge cycle time while maintaining device - 32 Minutes or Disable reliability. Automatic End-of-Charge Control: The PROG pin of the MCP73213 also serves as enable - Selectable Minimum Current Ratio: pin. When high impedance is applied, the MCP73213 5%, 7.5%, 10% or 20% will be in Standby mode. - Elapse Safety Timer: 4 hr, 6 hr, 8 hr or The MCP73213 is fully specified over the ambient Disable temperature range of -40C to +85C. The MCP73213 is available in a 10-lead DFN package.
