IS31FL3742A Overview
The IS31FL3742A is a general purpose 30×n (n=1~6) LED Matrix programmed via an I2C patible interface. Each LED can be dimmed individually with 8-bit PWM data and 8-bit 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, IS31FL3742A store the open or short information in Open-Short Registers.
