The IS31FL3746A is a general purpose 18×n (n=1~4) LED Matrix driver programmed via a 1MHz I2C compatible interface. Each LED can be dimmed individually with 8-bit PWM data and 8-bit DC scaling for color calibration, allowing 256 steps of linear PWM dimming and 256 steps of DC current adjustment. It features individual open and short LED detection, spread spectrum technology to reduce EMI, and a de-ghosting function. The device operates from a 2.7V to 5.5V supply voltage range.
