  • Switch Mode Li+ Battery SMBus Charge Controller HB6288
  • Outline

    The HB6288 is a high-efficiency, synchronous battery charger, offering low component count for space-constraint, multi-chemistry battery charging applications.
    The HB6288 uses two charge pumps to separately drive n-channel MOSFETs (ACFET, RBFET and BATFET) for automatic system power source selection.
    SMBus controlled input current, charge current, and charge voltage DACs allow for high regulation accuracies that can be programmed by the system power management micro-controller.
    The HB6288 uses internal input current register or external ILIM pin to throttle down PWM modulation to reduce the charge current.
    The HB6288 charges two, three or four series Li+ cells, and is available in a 20-pin, 4×4 mm2 QFN package.
