Notas de aplicación

  • Using the bqSWITCHER, bq24115, as a Nickel Charger
    PDF, 151 Kb, Archivo publicado: enero 5, 2007
    This application report describes the combination of the bqSWITCHERв„ў bq24115 charge management device and the bq2002 battery charge controller to provide a high-efficiency-switching charging solution for nickel battery packs.
  • Power Dissipation Analysis & Circuit Design for Sync Switching Battery Charger
    PDF, 402 Kb, Archivo publicado: mayo 31, 2005
    The bqSWITCHER(TM) (bq24100/03/05/08/13/15) is a highly integrated, switch-mode, Li-ion and Li-polymer battery charger IC. With two power MOSFETs, the gate drivers, and the controller fully integrated in the chip, the circuit design as well as the PCB layout has been appreciably simplified. However, it is still important to have a good understanding of the charger circuit design, layout principles
  • Implementations of Battery Charger and Power-Path Mgmt System Using bq241xx
    PDF, 752 Kb, Archivo publicado: jun 6, 2006
    This application report presents four system topologies that can be used to fully implement a portable power management system solution using the bqSWITCHERв„ў. Test results and the advantages and issues of each topology are discussed.
  • Drive High Current LEDs
    PDF, 437 Kb, Archivo publicado: enero 25, 2007
    This application report presents high-current LED driving requirements that use the TI integrated boost converter IC TPS6106x and integrated buck converter IC bqSWITCHERв„ў (bq2410x/11x/12x). Step-by-step design procedures, measurement results, and two dimming methods are provided and discussed.
