  Reducing Precharge Phase Region for bq24650
  PDF, 278 Kb, Archivo publicado: agosto 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

  A Discrete Narrow Voltage DC/DC Charger Solution for Multicell Batteries
  PDF, 123 Kb, Archivo publicado: dic 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

  Using the bq24650 to Charge a Sealed, Lead-Acid Battery (Rev. A)
  PDF, 157 Kb, Revisión: A, Archivo publicado: 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
