SINGLE-CHIP CHARGER AND DC/DC CONVERTER IC FOR BLUETOOTH HEADSETS  
AND OTHER PORTABLE APPLICATIONS (bqHYBRID™)  
FEATURES  
DESCRIPTION  
•
Li-Ion Or Li-Pol Charge Management and  
Synchronous DC-DC Power Conversion In a  
Single Chip  
The bqHYBRID™ series are highly integrated charge  
and power management devices targeted at  
space-limited bluetooth applications. The bqHYBRID  
series offer integrated power FET and current sensor  
for charge control, reverse blocking protection, high  
accuracy current and voltage regulation, charge  
status, charge termination, and a highly efficient and  
low-power dc-dc converter in a small package.  
•
•
Optimized for Powering Bluetooth Headsets  
and Accessories  
Charges and Powers the System from Either  
the AC Adapter or USB with Autonomous  
Power Source Selection  
The bqHYBRID charges the battery in three phases:  
conditioning, constant current and constant voltage.  
Charge is terminated based on minimum current. An  
internal charge timer provides a backup safety feature  
for charge termination. The bqHYBRID automatically  
re-starts the charge if the battery voltage falls below  
an internal threshold. The bqHYBRID automatically  
enters sleep mode when VCC supply is removed.  
•
•
Integrated USB Charge Control with  
Selectable 100 mA and 500 mA Charge Rates  
Integrated Power FET and Current Sensor for  
Up to 500 mA Charge Applications AND  
100 mA 1.8 V DC-DC Controller with  
Integrated FET  
•
•
Reverse Leakage Protection Prevents Battery  
Drainage  
The integrated low-power high-efficiency dc-dc con-  
verter is designed to operate directly from  
a
Automatic Power Save Mode For High  
Efficiency at Low Current, or Forced PWM for  
Frequency Sensitive Applications  
single-cell Li-Ion or Li-Pol battery pack. The output  
voltage is either adjustable from 0.7 V to VBAT  
(bq25010), fixed at 3.3 V (bq25011), or fixed at 1.8 V  
(bq25012), and is capable of delivering up to 150-mA  
of load current. The dc-dc converter operates at a  
synchronized 1 MHz switching frequency allowing for  
the use of small inductors.
