IS31FL3731
AUDIO MODULATED MATRIX LED DRIVER
May 2013
GENERAL DESCRIPTION
The IS31FL3731 is a compact LED driver for 144
single LEDs. The device can be programmed via an
I2C compatible interface. The IS31FL3731 offers two
blocks each driving 72 LEDs with 1/9 cycle rate. The
required lines to drive all 144 LEDs are reduced to 18
by using the cross-plexing feature optimizing space on
the PCB. Additionally each of the 144 LEDs can be
dimmed individually with 8-bit allowing 256 steps of
linear dimming.
To reduce CPU usage up to 8 frames can be stored
with individual time delays between frames to play
small animations automatically. LED frames can be
modulated with audio signal.
IS31FL3731 is available in QFN-28 (4mm × 4mm) and
SSOP-28 package. It operates from 2.7V to 5.5V over
the temperature range of -40°C to +85°C.
FEATURES
Supply voltage range: 2.7V to 5.5V
400kHz I2C-compatible interface
144 LEDs in dot matrix
Individual blink control
8 frames memory for animations
Picture mode and animation mode
Auto intensity breathing during the switching of
different frames
LED frames displayed can be modulated with
audio signal intensity
LED light intensity can be modulated with audio
signal intensity
QFN-28 (4mm × 4mm) and SSOP-28 package
APPLICATIONS
Mobile phones and other hand-held devices for
LED display
LED in home appliances
TYPICAL APPLICATION CIRCUIT
Figure 1
Typical Application Circuit
Note 1:
The IC should be placed far away from the mobile antenna in order to prevent the EMI.
Note 2:
The average current of each LED is 3.2mA when R
EXT
= 20kΩ. The LED current can be modulated by the R
EXT
. Please refer to the
detail information in Page 18
