IS31FL3751
DESCRIPTION
The IS31FL3751 is a general purpose 9×8 LED Matrix programmed via 1MHz I2C patible interface. Each LED can be dimmed individually with 12-bit PWM data and each LED can be dimmed with 4-bit DC scaling (Color Calibration) data which allowing 4096 steps of linear PWM dimming and 16 steps of DC current level adjustment.
Additionally each LED open and short state can be detected, IS31FL3751 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 IS31FL3751 operates from 2.7V to 5.5V and features a very low operational current.
IS31FL3751 is available in QFN-20 (4mm×4mm) package. It operates from 2.7V to 5.5V over the temperature range of -40°C to +125°C.
