SINGLE-CHIP SWITCHMODE, LI-ION AND LI-POLYMER CHARGE-MANAGEMENT  
IC WITH ENHANCED EMI PERFORMANCE(bqSWITCHER™)

FEATURES  
DESCRIPTION  
2
•
Enhanced EMI Performance  
•
•
•
Integrated Power FETs For Up To 2-A Charge  
Rate  
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.  
Suitable For 1-, 2-, or 3-Cell Li-Ion and  
Li-Polymer Battery Packs  
Synchronous Fixed-Frequency PWM  
Controller Operating at 1.1 MHz With 0% to  
100% Duty Cycle  
•
•
High-Accuracy Voltage and Current Regulation  
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.  
Status Outputs For LED or Host Processor  
Interface Indicates Charge-In-Progress, Charge  
Completion, Fault, and AC-Adapter Present  
Conditions  
•
20-V Absolute Maximum Voltage Rating on IN  
and OUT Pins  
•
•
•
Accurate High-Side Battery Current Sensing  
Battery Temperature Monitoring  
Automatic Sleep Mode for Low Power  
Consumption
