IS31FL3294 - Lumissil

IS31FL3294 4-LED LED DRIVER

The IS31FL3294 is a 4 LED current sink LED driver programmed via 1MHz I2C compatible interface. Each LED can be dimmed individually with 4096 steps PWM data and each current sink has 8-bit DC scaling (Color Calibration) data which allowing 4096 steps of linear PWM dimming and 256 steps of DC current adjustable level. The IS31FL3294 operates from 2.7V to 5.5V.

Features

a very low shutdown and operational current. The IS31FL3294 can operate in either “Current Level & PWM mode” or “Pattern” mode. In Current Level & PWM mode, the output current of each output is independently programmed and controlled in 4096 steps to achieve color mixing and the PWM duty cycle of each output is also independently programmed and controlled in 4096 steps to simplify color mixing or for smoothly diming control. In Pattern mode, the timing characteristics for RGB channels output can be individually adjusted to maintain a pre-established pattern sequence without requiring any addit.
