Single-chip Switchmode, Li-ion And Li-polymer Charge-management Ic With Enhanced Emi Performance

  The bqSWITCHER? series are highly integrated Li-ion and Li-polymer switch-mode charge management devices targeted at a wide range of portable applications. The bqSWITCHER? series offers integrated synchronous PWM Controller and power FETs high-accuracy current and voltage regulation, charge preconditioning, charge status, and charge termination, in a small, thermally enhanced QFN package. The bqSWITCHER charges the Battery in three phases: conditioning, constant current, and constant voltage. Charge is terminated based on userselectable minimum current level. A programmable charge Timer provides a safety backup for charge termination. The bqSWITCHER automatically restarts the charge cycle if the Battery voltage falls below an internal threshold. The bqSWITCHER automatically enters sleep mode when VCC supply is removed.
