Description

The BQ24103RHLR series are highly integrated Li-ion and Li-polymer switch-mode charge management devices targeted at a wide range of portable applications. The BQ24103RHLR 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 system-controlled version provides additional inputs for full charge management under system control.The BQ24103RHLR 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 BQ24103RHLR automatically re-starts the charge cycle if the battery voltage falls below an internal threshold. The BQ24103RHLR automatically enters sleep mode when VCC supply is removed. BQ24103RHLR Features • Ideal For High-Efficient Charger Designs For Single-, Two- or Three-Cell Li-Ion and Li-Pol Battery Packs• Integrated Synchronous Fixed-Frequency PWM Controller Operating at 1.1 MHz with 0 to 100% Duty Cycle• Integrated PowerFETs For Up To 2-A Charge Rate• High-Accuracy Voltage and Current Regulation• Available In Both Stand-Alone (Built-In Charge Management and Control) and System-Controlled (Under System Command) Versions• 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 Current Sensing• Optional Battery Temperature Monitoring• Automatic Sleep Mode for Low Power Consumption• System-Controlled Version Can Be Used In NiMH and NiCd Applications• Uses Ceramic Capacitors• Reverse Leakage Protection Prevents Battery Drainage• Thermal Shutdown and Protection• Built-In Battery Detection BQ24103RHLR Applications • Handheld Products• Portable Media Players• Industrial and Medical Equipment• Portable Equipment
