  • Reducing Precharge Phase Region for bq24650
    PDF, 278 Kb, 档案已发布: Aug 30, 2011
    The bq24650 is a battery charger operates in three phases: precharge phase, fast-charge current regulation, and fast-charge voltage regulation. In many applications, a long precharge region is not required when using bq24650 as a charger. Thus, the following application note describes a method of reducing the precharge region for this charger. In this method, a circuit is designed to force the vol
  • Using the bq24650 to Charge a LiFePO4 battery
    PDF, 144 Kb, 档案已发布: Aug 24, 2010
    This application report gives an example of using the bq24650 charge management device to provide a high-efficiency, switching-mode charging solution for the LiFePO4 battery.
  • A Discrete Narrow Voltage DC/DC Charger Solution for Multicell Batteries
    PDF, 123 Kb, 档案已发布: Dec 12, 2011
    Solar charging applications typically require an input voltage regulation due to large variations in solar celllighting condition. Combining an NVDC (narrow voltage dc/dc) battery charging architectures with solar cell charging can extend battery life and run times by maintaining a very narrow voltage range for the system power. This application report shows how to do a NVDC charger solution wit
  • Maximum Power Point Tracking With the bq24650 Charger. (Rev. A)
    PDF, 474 Kb, 修订版: A, 档案已发布: Aug 15, 2011
    This application report describes a solution to track the maximum power point of a solar panel using a negative temperature coefficient (NTC) thermistor with the bq24650.

  • Using the bq24650 to Charge a Sealed, Lead-Acid Battery (Rev. A)
    PDF, 157 Kb, 修订版: A, 档案已发布: Oct 4, 2011
    This application report shows how to modify the bq24650 to charge a sealed, lead-acid battery from a solar panel. The circuit uses constant current (CC) charging to reach the bulk battery voltage and then switches to constant voltage (CV) charging until the termination current is reached. The modifications necessary to change the regulated voltage, recharge voltage and regulated current are discus
