Texas Instruments BQ24108RHLR

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.
