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 bq241xxPDF, 752 Kb, Datei veröffentlicht: 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 LEDsPDF, 437 Kb, Datei veröffentlicht: Jan 25, 2007
