IS31FL3737 - 12x12 DOTS MATRIX LED DRIVER

Key Features

  • The IS31FL3737 is a general purpose 12×12 LEDs matrix driver with 1/12 cycle rate. The device can be programmed via an I2C compatible interface. Each LED can be dimmed individually with 8-bit PWM data which allowing 256 steps of linear dimming. IS31FL3737 features 3 Auto Breathing Modes which are noted as ABM-1, ABM-2 and ABM-3. For each Auto Breathing Mode, there are 4 timing characters which include current rising / holding / falling / off time and 3 loop characters which include Loop-Beginni.
