Application Notes
- Reducing Precharge Phase Region for bq24650PDF, 278 Kb, File published: 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 batteryPDF, 144 Kb, File published: 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 BatteriesPDF, 123 Kb, File published: 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, Revision: A, File published: 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. 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, File published: Sep 19, 2016
