SLUS606N – JUNE 2004 – REVISED NOVEMBER 2008 SYNCHRONOUS SWITCHMODE, LI-ION AND LI-POLYMER CHARGE-MANAGEMENT IC WITH INTEGRATED POWER FETs (bqSWITCHER™) 23 • Ideal For Highly Efficient Charger Designs For The bqSWITCHER™ series are highly integrated Single-, Two- or Three-Cell Li-Ion and Li-ion and Li-polymer switch-mode charge Li-Polymer Battery Packs management devices targeted at a wide range of portable applications. The bqSWITCHER™ series • bq24105 Also for LiFePO 4Battery (see Using offers integrated synchronous PWM controller and bq24105 to Charge the LiFePO4 Battery) power FETs, high-accuracy current and voltage • Integrated Synchronous Fixed-Frequency regulation, charge preconditioning, charge status, and PWM Controller Operating at 1.1 MHz With 0% charge termination, in a small, thermally enhanced to 100% Duty Cycle QFN package. The system-controlled version provides additional inputs for full charge management • Integrated Power FETs For Up To 2-A Charge under system control. Rate • High-Accuracy Voltage and Current Regulation The bqSWITCHER charges the battery in three phases: conditioning, constant current, and constant • Available In Both Stand-Alone (Built-In Charge voltage. Charge is terminated based on user- Management and Control) and selectable minimum current level. A programmable System-Controlled (Under System Command) charge timer provides a safety backup for charge Versions termination. The bqSWITCHER automatically restarts • Status Outputs For LED or Host Processor the charge cycle if the battery voltage falls below an Interface Indicates Charge-In-Progress, Charge internal threshold. The bqSWITCHER automatically enters sleep mode when VCC supply is removed. Completion, Fault, and AC-Adapter Present Conditions RHL PACKAGE • 20-V Maximum Voltage Rating on IN and OUT (TOP VIEW) (bq24100, 03, 03A, 04, 05, 08, 09, 13, 13A, 15) Pins • High-Side Battery Current Sensing • Battery Temperature Monitoring • Automatic Sleep Mode for Low Power Consumption • System-Controlled Version Can Be Used In NiMH and NiCd Applications • 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 Package • Handheld Products • Portable Media Players • Industrial and Medical Equipment • Portable Equipment 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 bqSWITCHER, PowerPAD are trademarks of Texas Instruments. 3 All other trademarks are the property of their respective owners.
