IS31FL3741A - Lumissil

IS31FL3741A 39x9 DOTS MATRIX LED DRIVER

The IS31FL3741A is a general purpose 39×9 LED Matrix programmed via an I2C compatible 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, IS31FL3741A store the open or s.
