应用须知

  • High Efficiency Dual Chemistry Charger Using the bq2000
    PDF, 130 Kb, 档案已发布: Sep 5, 1999
    In this example, the bq2000 is used to design a simple and cost-effective chemistry-independent charger. This implementation is suitable for any application requiring a high efficiency charge management in a small footprint.
  • Bq2000 in Constant Voltage Phase for Li-ion Battery
    PDF, 533 Kb, 档案已发布: Oct 31, 2011
    The bq2000 charger can be used to charge Li-Ion, NiCd, or NiMH batteries. It uses three charging modes, the pre-charge, fast charge, and termination mode. It detects the battery chemistry type during the fast charge mode by monitoring the battery voltage profile. Once the chemistry is determined, the part completes the fast charge algorithm for the appropriate chemistry type. For Li-Ion batteries,
