IS31FL3741 - 39 x 9 DOTS MATRIX LED DRIVER

General Description

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.

Key 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.  .

IS31FL3741 39×9 DOTS MATRIX LED DRIVER Preliminary Information September 2017 GENERAL DESCRIPTION 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.
