  • Outline

    HB6298B is an integrated 1-cell/2-cell
    Li-ion/Li polymer switch-mode charge management
    device, targeted at a wide range of portable
    applications. HB6298B offers integrated power FET,
    high-accuracy current and voltage regulation,
    charge preconditioning, charge status, and charge
    termination, in a small TSSOP20 or QFN20 package.
    HB6298B charges the battary in three phase:
    preconditioning, constant current(CC), and
    constant voltage(CV). The charge current is
    programmable with an external resistor up to
    1.5A. HB6298B features cycle-by-cycle current
    limit, charge current thermal foldback and short
    circuit protection to guarantee safe operation.
    Additional features include NTC thermistor
    interface to monitor the battery temperature.
