Notas de aplicación
- Reducing Precharge Phase Region for bq24650PDF, 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 - Using the bq24650 to Charge a LiFePO4 batteryPDF, 144 Kb, Archivo publicado: agosto 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 BatteriesPDF, 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 - Maximum Power Point Tracking With the bq24650 Charger. (Rev. A)PDF, 474 Kb, Revisión: A, Archivo publicado: agosto 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. The basic functionality of a solar panel is described. The use of a spreadsheet tool to aid in the setup process is described as well. - Preventing bq24650 Leakage Current When Using Shaded Solar PanelsPDF, 2.3 Mb, Archivo publicado: sept 19, 2016
- 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 - bq246xx Device ComparisonPDF, 37 Kb, Archivo publicado: oct 8, 2010
