The BQ24103RHLR is a highly integrated Li-ion and Li-polymer switch-mode Charge Management Device 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. 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.
