Description
General part information
TLC59581 Series
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.
