SLED17331 series have four types of built-in LED matrix. The chip can drive up to
256 LED lights and 75 RGB LED lights. In the LED matrix of SLED17331 series, each
LED has on / off, blinking, breathing light and audio input, automatic synchronization
and many other functions. The PWM (pulse width modulation) technology incorporated
in the chip can provide 256-level brightness adjustment and it also equipped with
16-level dot correction function. In addition, SLED17331 also supports automatic detection
technology and two stage of temperature detectors.
SLED17331 series with the features of multi-channel, constant current and PWM.
The SLED17331 provides per channel constant current range from 8mA to 40mA, and the
output current channel can be adjusted through the 64-level internal register. The
series also supports 2.7V to 5V power supply system and the sink current is up to
320mA per output channel.
