BQ24105RHLR Datasheet PDF - TI

The BQ24105RHLR is a standalone synchronous switch-mode Li-ion Charger with 2A FET. It 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. 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.

● 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.
