IS31FL3739
DESCRIPTION
The IS31FL3739 is a general purpose 8×8 or 7×9 matrix LED driver programmed via a 1MHz I2C bus patible 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 bination enables 256 steps of linear PWM dimming for each dot and 256 steps of DC current adjustment for each CSx.
Additionally, the open or short state of each LED can be detected and stored in Open-Short Registers. The MCU can then read the Open-Short Registers via the I2C bus and identify which LED in the array is open or short.
The IS31FL3729 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.
