Overview
The IS31FL3741 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, IS31FL3741 store the open or short
information in Open-Short Registers. The Open-Short
Registers allowing MCU to read out via I2C
compatible 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.
