FEATURES  
DESCRIPTION  
D
Ideal For High-Efficient Charger Designs For  
Single-, Two- or Three-Cell Li-Ion and Li-Pol  
Battery Packs  
The bqSWITCHERseries are highly integrated  
Li−Ion and Li−Pol switch−mode charge  
management devices targeted at a wide range of  
portable applications. The bqSWITCHERseries  
offer integrated synchronous PWM controller and  
PowerFETs, 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.  
D
Integrated Synchronous Fixed-Frequency  
PWM Controller Operating at 1.1 MHz with 0  
to 100% Duty Cycle

D
Integrated PowerFETs For Up To 2-A Charge  
Rate  
High-Accuracy Voltage and Current  
Regulation  
Available In Both Standalone (Built-In  
Charge Management and Control) and  
System-Controlled (Under System  
Command) Versions  
The bqSWITCHER charges the battery in three  
phases: conditioning, constant current, and  
constant voltage. Charge is terminated based on  
user−selectable minimum current level.

programmable charge timer provides a safety  
backup safety for charge termination. The  
bqSWITCHER automatically re-starts the charge  
cycle if the battery voltage falls below an internal  
threshold. The bqSWITCHER automatically
