  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

  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
