IS31FL3766
DESCRIPTION
The IS31FL3766 is a general purpose 18 × 6 (n=1~6) LED Matrix programmed via 1MHz I2C patible interface. Each LED can be dimmed individually with 12-bit/8+4-bit/8-bit/6+2-bit PWM data and each color sink can have 8-bit DC scaling data which allowing 256 steps of linear PWM dimming and each color sink has 256 steps of DC current adjustable level and precision for smooth LED brightness control. The maximum output current of each channel is designed to be 40m A, which can be adjusted by 8-bit global control register.
Additionally, each LED open and short state can be detected, IS31FL3766 stores the open or short information in Open-Short Registers. The Open-Short Registers allow MCU to read out via I2C patible interface. Inform MCU whether there are LEDs open or short and the locations of open or short LEDs. Proprietary algorithms are used in IS31FL3766 to minimize power bus noise caused by passive ponents on the power bus such as MLCC decoupling capacitor. All registers can...
