SLUS721A 鈥?DECEMBER 2006 鈥?REVISED MARCH 2007
SINGLE-CHIP CHARGER AND DC/DC CONVERTER IC FOR PORTABLE APPLICATIONS
FEATURES
鈥?/div>
Li-Ion Or Li-Pol Charge Management and
Synchronous DC-DC Power Conversion In a
Single Chip
Charges and Powers the System from Either
the AC Adapter or USB with Autonomous
Power Source Selection
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
300 mA DC-DC Controller with Integrated
FETs
Reverse Leakage Protection Prevents Battery
Drainage
Automatic Power Save Mode For High
Efficiency at Low Current, or Forced PWM for
Frequency Sensitive Applications
DESCRIPTION
The bq25015/7 are highly integrated charge and
power
management
devices
targeted
at
space-limited bluetooth applications. The bq25015/7
devices 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.
The bq25015/7 devices charge 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 bq25015/7
automatically re-starts the charge if the battery
voltage falls below an internal threshold. The
bq25015/7 automatically enters sleep mode when
V
CC
supply is removed.
The integrated low-power high-efficiency dc-dc
converter is designed to operate directly from a
single-cell Li-ion or Li-Pol battery pack. The output
voltage is either adjustable from 0.7 V to VBAT, or
fixed at 1.8 V (bq25017) and is capable of delivering
up to 300-mA of load current. The dc-dc converter
operates at a synchronized 1 MHz switching
frequency allowing for the use of small inductors.
