Notas de aplicación

  • bq24080 Single Cell Li-Ion Battery Charger with Modified Precharge
    PDF, 123 Kb, Archivo publicado: enero 25, 2008
    This application report demonstrates an easy way to modify the precharge current level and the fast-charge current level. Some applications may require the system to run below the VLOWV threshold, 3 V, where the precharge current is programmed to one-tenth of the fast-charge current. The precharge current may not be sufficient to charge the cell and power the system and may not need to

    PDF, 110 Kb, Archivo publicado: abr 29, 2009
    By changing standard 4.2-V charge voltage to 4.1 V or lower, rechargeable lithium-ion (Li-ion) battery cycle life can be extended at low temperature. For new chemistry such as LiFePO4 rechargeable battery, it requires 3.6-V charge voltage. All these new applications need a nonstandard charge voltage. This application report gives examples of using the 4.2-V bq24085 charger to achieve different cha
