Application Notes
- Achieving Different Charge Voltage for bq2408xPDF, 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 - How to Achieve Power-Path Management Function for bq2408x (Rev. A)PDF, 174 Kb, Revision: A, File published: Apr 21, 2009
This application report presents a simple external circuit for achieving a power-path management function while maintaining an overvoltage protection function and blocking reverse current for low-cost linear battery chargers such as the bq2408x . Brief design criteria and a trade-off study with test results are presented.
