    产品信息

    描述The bqSWITCHER™ series are highly integrated Li-ion and Li-polymer switch-mode charge management devices 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, in a small, thermally enhanced QFN package.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.特性 Qualified for Automotive Applications Ideal For Highly Efficient Charger Designs For Single-, Two-, or Three-Cell Li-Ion and Li-Polymer Battery Packs Also for LiFePO4 Battery (see Using bq24105 to Charge LiFePO4 Battery) Integrated Synchronous Fixed-Frequency PWM Controller Operating at 1.1 MHz With 0% to 100% Duty Cycle Integrated Power FETs For Up To 2-A Charge Rate High-Accuracy Voltage and Current Regulation Stand-Alone (Built-In Charge Management and Control) Version Status Outputs For LED or Host Processor Interface Indicates Charge-In-Progress, Charge Completion, Fault, and AC-Adapter Present Conditions 20-V Maximum Voltage Rating on IN and OUT Pins 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 Available in 20-Pin, 3.5 mm × 4.5 mm, QFN PackageAll trademarks are the property of their respective owners.
