The IS31FL3751 is a compact 4x16 or 2x32 LED matrix driver with an I2C compatible interface. It features individual 8-bit PWM control for grayscale dimming (256 steps) and individual 8-bit DC current scaling for brightness balance (256 steps). The device supports a global current setting with 255 steps and includes built-in de-ghosting and individual LED open/short detection. It is designed for battery-powered or space-constrained applications with a wide supply voltage range and low shutdown current.
