BQ24123RHLTG4

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

The BQ24123RHLTG4 is a synchronous switch-mode 2-cell Li-ion Charger with 2A FET and enhanced EMI performance. The bqSWITCHER™ series offers integrated synchronous PWM controller and power FETs, high-accuracy current and voltage regulation, charge preconditioning, charge status and charge termination. It 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. It automatically restarts the charge cycle if the battery voltage falls below an internal threshold and automatically enters sleep mode when VCC supply is removed.
