  • Outline

    The HB6293 series are highly integrated Li-ion and Li-polymer switch-mode charge management devices targeted at a wide range of portable applications. The HB6293 series offers high-accuracy current and voltage regulation, charge preconditioning, charge status, and charge termination, in a small, thermally enhanced MSOP-10 package. The HB6293 charges the battery in three phases: pre-charge, constant current and constant voltage, constant current is decided by the external resistance, and the constant voltage can be fine-tuned by external resistance. Protections of over voltage and short circuit provide a safety backup for charge termination. The HB6293 automatically restarts the charge cycle if the battery voltage falls below an internal threshold and enters sleep mode when VCC supply is removed.
