产品概述
The bqSWITCHER™ series are highly integrated Li-ion and
Li-polymer switched-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 user-selectable 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.
