应用须知

  • Power Dissipation Analysis & Circuit Design for Sync Switching Battery Charger
    PDF, 402 Kb, 档案已发布: May 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, 档案已发布: 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.
