MY9168 - 16-Channel Constant Current LED Driver

This page provides the datasheet information for the MY9168, a member of the MY9168-MY 16-Channel Constant Current LED Driver family.

Description

The MY9168 16-channel c o n s t a n t c u r r e n t LED driver w i t h g h o s t i m a g e a b a t e m e n t i s s u i t a b l e for multiplexing display system.

Features

  • a f a s t 30MHz DCK input, allowing a wide LED dimming (on/off) range to be implemented. The MY9168 offers a 4-wire serial interface, a 16-bit shift register, and a 16-bit transparent latch. The serial interface allows a microcontroller to configure the output channels using four inputs (DI, DCK, LAT, and ENB) and a data output (DO). DO allows multiple drivers to be casca.

MY-Semi Preliminary MY9168 16-Channel Constant Current LED Driver With Ghost Image Abatement General Description The MY9168 16-channel c o n s t a n t c u r r e n t LED driver w i t h g h o s t i m a g e a b a t e m e n t i s s u i t a b l e for multiplexing display system. The device h a s w i d e s u p p l y v o l t a g e r a n g e ( 3.0V ~ 5.5V) and provides 1 6 open-drain constant current sinking outputs that are rated to 1 6 V and delivers up to 55mA of high accuracy current to each string of LED. The current at each output is programmable by means of an external current-sensing resistor. The MY9168 features a f a s t 30MHz DCK input, allowing a wide LED dimming (on/off) range to be implemented.
