IS31FL3741
IS31FL3741 is 39 x 9 DOTS MATRIX LED DRIVER manufactured by ISSI.
DESCRIPTION
The IS31FL3741 is a general purpose 39×9 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, IS31FL3741 store the open or short information in Open-Short Registers. The Open-Short Registers allowing MCU to read out via I2C patible interface. Inform MCU whether there are LEDs open or short and the locations of open or short LEDs.
The IS31FL3741 operates from 2.7V to 5.5V and features a very low shutdown and operational current.
IS31FL3741 is available in QFN-60 (7mm×7mm) package. It operates from 2.7V to 5.5V over the temperature range of -40°C to +125°C.
