bq2412x Single-Chip Switched-Mode, Li-Ion, and Li-Polymer Charge-Management With Enhanced EMI Performance (bqSWITCHER™) Features 2 Applications Enhanced EMI Performance • Handheld Products Integrated Power FETs For Up To 2-A Charge • Portable Media Players
Rate • Industrial and Medical Equipment Suitable For1-, 2-,or 3-Cell Li-Ion and Li-Polymer • Portable EquipmentBattery Packs • Portable DVD Players Synchronous Fixed-Frequency PWM Controller
Operatingat 1.1 MHz With 0%to 100% Duty
3 DescriptionCycle The bqSWITCHER™ series are highly integrated Li- High-Accuracy Voltage and Current Regulation ion and Li-polymer switched-mode charge
management devices targeted ata wide range of• Status Outputs For LEDor Host Processor portable applications. The bqSWITCHER™ seriesInterface Indicates Charge-In-Progress, Charge offers integrated synchronous PWM controller andCompletion, Fault, and AC-Adapter Present power FETs, high-accuracy current and voltageConditions regulation, charge preconditioning, charge status, and• 20-V Absolute Maximum Voltage RatingonIN and charge termination,ina small, thermally enhanced
OUT Pins QFN package. Accurate High-Side Battery Current Sensing The bqSWITCHER charges the battery in three Battery Temperature Monitoring phases: conditioning, constant current, and constant
voltage. Charge is terminated based on user-• Automatic Sleep Modefor Low Power selectable minimum current level.A programmableConsumption charge timer providesa safety backup for charge• Reverse Leakage Protection Prevents Battery termination. The bqSWITCHER automatically restartsDrainage the charge cycleif the battery voltage falls below an
internal threshold. The bqSWITCHER automatically• Thermal Shutdown and Protection
enters sleep mode when VCC supplyis removed.• Built-In Battery Detection Availablein 20-pin 3.5-mm× 4.5-mm VQFN
