Product details

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.

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 modulation method to increase the visual refresh rate up to 10.
