具有 5V–28V VCC 输入的独立同步开关模式锂离子或锂聚合物电池充电器

BQ24610产品信息

描述 The bq2461x is a highly integrated Li-ion or Li-polymer switched-mode battery charge controller. The device offers a constant-frequency synchronous switching PWM controller with high-accuracy charge current and voltage regulation, charge preconditioning, termination, adapter current regulation, and charge status monitoring. The bq2461x charges the battery in three phases: preconditioning, constant current, and constant voltage. Charge is terminated when the current reaches a minimum user-selectable level. A programmable charge timer provides a safety backup. The bq2461x automatically restarts the charge cycle if the battery voltage falls below an internal threshold, and enters a low quiescent current sleep mode when the input voltage falls below the battery voltage.特性600-kHz NMOS-NMOS Synchronous Buck ConverterStand-Alone Charger Support for Li-Ion or Li- Polymer5-V to 28-V VCC Input Operating Range and Supports 1- to 6-Battery Cells (bq24610)5-V to 24-V VCC Input Operating Range and Supports 1- to 5-Battery Cells (bq24617)Up to 10-A Charge Current and Adapter CurrentHigh-Accuracy Voltage and Current Regulation &plusm;0.5% Charge Voltage Accuracy&plusm;3% Charge Current Accuracy&plusm;3% Adapter Current AccuracyIntegration Automatic System Power Selection From Adapter or BatteryInternal Loop Compensation and Soft StartDynamic Power ManagementSafety Protection Input Overvoltage ProtectionBattery Thermistor Sense Hot and Cold Charge SuspendBattery DetectionReverse Protection Input FETProgrammable Safety TimerCharge Overcurrent ProtectionBattery Short ProtectionBattery Overvoltage ProtectionThermal ShutdownStatus Outputs Adapter PresentCharger Operation StatusCharge Enable Pin6-V Gate Drive for Synchronous Buck Converter30-ns Driver Dead-Time and 99.5% MaximumEffective Duty CycleEnergy Star Low Quiescent Current Iq< 15-µA Off-State Battery Discharge Current< 1.5-mA Off-State Input Quiescent CurrentAPPLICATIONSNetbooks, Mobile Internet Devices, and Ultra- Mobile PCsPersonal Digital Assistants (PDAs)Handheld TerminalsIndustrial and Medical EquipmentPortable Equipment All other trademarks are the property of their respective owners
