IS31FL3252 Overview
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 Open Short Registers allowing MCU to read out via...
