    Applications

    • Netbook PC
    • Distributed Power Systems
    • Chargers for 2-Cell or 3-Cell Li-Ion Batteries

    Design Notes

    • Charge current accuracy depends on the sense resistor tolerance, so use a 1% or better part and keep its traces Kelvin-connected.
    • Wire the NTC input for JEITA profile control if the pack is charged over temperature.
    • Set the input current limit to what the adapter can actually deliver; a limit above the adapter rating causes the input rail to collapse mid-charge.
    • Termination current and recharge threshold dominate cycle life in shallow-cycling products.
