IS31FL3252
DESCRIPTION
The IS31FL3252 is a 12 LED current sinks LED driver programmed via 1MHz I2C patible interface. Each LED can be dimmed individually with 16-bit PWM data and each color current sinks has 8-bit group DC scaling (Color Calibration) data which allowing 65536 steps of linear PWM dimming for each channel and 256 steps of DC current adjustable level for each color group. The output current of each channel can be set at up to 27.5m A (max.), all channels are grouped as G group (OUT1, OUT4, OUT7...), R group (OUT2, OUT5, OUT8...), B group (OUT3, OUT6, OUT9...) and each group has 8 bits output current control register which allows fine tuning the current for rich global RGB color mixing.)
Additionally each LED open and short state can be detected, IS31FL3252 stores the open or short information in Open Short Registers. The Open Short Registers allowing MCU to read out via I2C patible interface. Inform MCU whether there are LEDs open or short and the locations of open or short...
