MCP73113/4 Single-Cell Li-Ion/Li-Polymer Battery Charge Management Controller with Input Overvoltage Protection Features: Description: Complete Linear Charge Management Controller: The MCP73113/4 are highly integrated Li-Ion battery charge management controllers for use in - Integrated Input Overvoltage Protection space-limited and cost-sensitive applications. The - Integrated Pass Transistor MCP73113/4 devices provide specific charge - Integrated Current Sense algorithms for Li-Ion/Li-Polymer batteries to achieve - Integrated Reverse Discharge Protection optimal capacity and safety in the shortest charging Constant Current/Constant Voltage Operation time possible. Along with their small physical size, the with Thermal Regulation low number of external components make the MCP73113/4 ideally suitable for portable applications. 4.15V Undervoltage Lockout (UVLO) The absolute maximum voltage, up to 18V, allows the 18V Absolute Maximum Input with OVP: use of MCP73113/4 in harsh environments, such as - 6.5V (MCP73113) low cost wall wart or voltage spikes from plug/unplug. - 5.8V (MCP73114) The MCP73113/4 devices employ a constant current/ High Accuracy Preset Voltage Regulation Through constant voltage charge algorithm. The various Full Temperature Range (-5C to +55C): +0.5% charging voltage regulations provide design engineers Battery Charge Voltage Options: flexibility to use in different applications. The fast charge, constant current value is set with one external - 4.10V, 4.20V, 4.35V or 4.4V resistor from 130 mA to 1100 mA. The MCP73113/4 Resistor Programmable Fast Charge Current: devices limit the charge current based on die - 130 mA-1100 mA temperature during high power or high ambient Preconditioning of Deeply Depleted Cells: conditions. This thermal regulation optimizes the - Available Options: 10% or Disable charge cycle time while maintaining device reliability. Integrated Precondition Timer: The PROG pin of the MCP73113/4 also serves as - 32 Minutes or Disable enable pin. When high-impedance is applied, the Automatic End-of-Charge Control: MCP73113/4 will be in Standby mode. - Selectable Minimum Current Ratio: The MCP73113/4 devices are fully specified over the 5%, 7.5%, 10% or 20% ambient temperature range of -40C to +85C. They are available in a 10-lead, DFN package. - Elapse Safety Timer: 4 HR, 6 HR, 8 HR or Disable Package Types (Top View) Automatic Recharge: - Available Options: 95% or Disable MCP73113/4 Charge Status Output-Two Style Options 3x3 DFN * Soft Start V 1 10 PROG DD Temperature Range: -40C to +85C Packaging: DFN-10 (3 mm x 3 mm) V 2 9 V DD SS EP V 3 8 V BAT SS 11 Applications: V 4 7 STAT BAT NC NC 5 6 Low-Cost Li-Ion/Li-Poly.
