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.
● Enhanced EMI performance
● High-accuracy voltage and current regulation
● High-side battery current sensing
● Battery temperature monitoring
● Automatic sleep mode for low power consumption
● Reverse leakage protection prevents battery drainage
● Thermal shutdown and protection
● Built-in battery detection
● Green product and no Sb/Br
●Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
