IS31FL3737B 12 x 12 Dots Matrix LED Driver Lumissil IS31FL3737B 12 x 12 Dots Matrix LED Driver is a general-purpose LED driver with 1/12 cycle rate that requires 2.7V to 5.5V supply voltage range. This dot-matrix LED driver operates over the temperature range of -40°C to 125°C. The IS31FL3737B LED driver can be programmed via an I2C compatible interface. Each LED can be dimmed individually with 8-bit PWM data which allows 256 steps of linear dimming. The IS31FL3737B LED driver features 3 Auto Breathing Modes which are noted as ABM-1, ABM-2, ABM-3. Each ABM has 4 breathing characters which include current rising/ falling/ holding/ off-time and 3 loop characters which include loop-beginning/ loop-ending/ loop-times. The IS31FL3737B driver incorporates LEDs that can be configured individually to ABM or No-breathing mode. This driver detects each LED's open and short state and stores the open or short information in open-short registers. These registers inform MCU whether the LEDs are open or short and the location of these open or short LEDs. The open-short registers allow MCU to read via an I2C interface. The IS31FL3737B driver is available in QFN-40 (5mm x 5mm) package. Typical applications include LED in white goods application, gaming device (keyboard and mouse), and hand-held device for the LED display.
