3 Description
The TLC59581/82are 48-channel constant-current
sink drivers. Each channel has an individually-
adjustable, 65536-step, pulse width modulation
(PWM) grayscale (GS) brightness control.
The TLC59581 can support 32-multiplexing while
TLC59582 can support 16-multiplexing.
The output channels are divided into three groups.
Each group has a 512-step color brightness control
(CC). CC adjusts brightness control between colors.
The maximum current value of all 48 channels can be
set by 8-step global brightness control (BC). BC
adjusts brightness deviation between LED drivers.
GS, CC and BC data are accessible through a serial
interface port.
See application note Build High Density, High
Refresh Rate, Multiplexing LED Panel with
TLC59581, SLVA744.
