产品概述
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 VQFN package. The system-controlled version provides additional inputs
for full charge management under system control.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.
