General Description

The MY9221, 12-channels (R/G/B x 4) c o n s t a n t current APDM (Adaptive Pulse Density M o d u l a t i o n ) LED driver, operates over a 3V ~ 5.5V input voltage range.

The device provides 1 2 open-drain constant current sinking outputs that are rated to 1 7 V and delivers up to 60mA of high accuracy current to each string of LED.

The current at each output is programmable by means of three external current setting resistors.

Overview

MY-Semi MY9221 12-Channel LED Driver With Grayscale Adaptive Pulse Density Modulation Control.

Key Features

  • a 1 0 M H z E M I r e d u c t i o n data clock input. MY9221 also offers a 2-wire serial interface to send the grayscale data, control command including 16/14/12/8-bit grayscale selection, grayscale clock frequency division selection, output polarity selection for high power LED driving, output Tr/Tf timing selection, current output waveform selection, and to realize the internal-latch function. MY9221 provides adaptive pulse density.
