  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

  Achieving Different Charge Voltage for bq2408x
  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
