Achieving Different Charge Voltage for bq2408x
PDF, 110 Kb, File published: Apr 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
