16 channel 256 level brightness LED Drivers
GENERAL DESCRIPTION
The BCT3299 is a LED driver with independent 16
output channels, and the output current of each
channel can be programmed to achieve 256 level,
with maximum up to 30 mA.
The device is equipped with an internal program
memory, which allows the operation without
processor control. Each channel is independently
programmed to on, off, gradually light up or down
over time. In audio mode, the brightness of each
channel can be proportional to the strength of the
audio signal, also there will be the PWM output
which sync to the audio signal. BCT3299 is
designed to produce versatile lighting effects for
portable devices.
Less than 2uA chip off current effective extend
battery usage time, BCT3299 is lead-free
environmental protection products, and the
temperature range is -40 to + 85 . It has
QFN-24 (4 x 4 mm) package, with the thickness of
0.75 mm.
FEATURES
16 channel constant current drive, each
channel maximum output current of 30mA
and maximum output current can be set by
external Rext
Each channel has 256 level, programmed by
SPI interface.
Built-In POR(Power On reset) function
Co-Anode LED level connection
Four frequency PWM output can be chosen
from
2.7V-5.5V power supply range wide
QFN-24 (4 mm x 4 mm) package
APPLICATIONS
Mobile phone
MP3/MP4/CD/Media Players
Toys
Feature home appliance

NOTE:
Stresses beyond those listed under “Absolute Maximum Ratings” may
cause permanent damage to the device. These are stress ratings only,
and functional operation of the device at these or any other conditions
beyond those indicated in the operational sections of the specifications
is not implied. Exposure to absolute maximum rating conditions for
extended periods may affect device reliability.
CAUTION
This integrated circuit can be damaged by ESD if you don’t pay
attention to ESD protection. Broadchip recommends that all integrated
circuits be handled with appropriate precautions. Failure to observe
proper handling and installation procedures can cause damage. ESD
damage can range from subtle performance degradation to complete
device failure. Precision integrated circuits may be more susceptible to
damage because very small parametric changes could cause the
device not to meet its published specifications.
Broadchip reserves the right to make any change in circuit design,
specification or other related things if necessary without notice at any
time. Please contact Broadchip sales office to get the latest datasheet.
