IS31FL3745 Description
The IS31FL3745 is a general purpose 18×n (n=1~8) LED Matrix programmed via 1MHz I2C patible interface. Each LED can be dimmed individually with 8-bit PWM data and 8-bit DC scaling data which allowing 256 steps of linear PWM dimming and 256 steps of DC current adjustable level. Additionally each LED open and short state can be detected, IS31FL3745 store the open or short information in Open-Short Registers.
