Описание
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
