IS31FL3739 - Lumissil

IS31FL3739 8x8 / 7x9 MATRIX LED DRIVER

The IS31FL3739 is a general purpose 8×8 or 7×9 matrix LED driver programmed via a 1MHz I2C bus compatible interface. Each LED can be dimmed individually with 8-bit PWM data, and each CSx has 8-bit DC current scaling for color calibration. The combination enables 256 steps of linear PWM dimming for each dot and 256 steps of DC current adjustment for each CSx..

Features

a very low shutdown and quiescent (operational) current. It also supports selectable noise reduction features such as PWM clock spread spectrum and 180 degree phase shifting. IS31FL3739 is available in SOP-24 package. It operates from 2.7V to 5.5V over the full temperature range of -40°C to +125°C. January 2021 FEATURES
