Зарядные ИС для аккумуляторов BQ24103RHLR

Зарядное устройство для 2-элементной литий-ионной , Li-Pol батареи, 16В вход, 8.4В/2A зарядка, QFN-20

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.
