Introduction
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
