–

20 mA at 3.3 VCC

The TLC59581 can support 32-multiplexing while

•

Global Brightness Control (BC): 3-Bit (8-Step)

TLC59582 can support 16-multiplexing.

•

Color Brightness Control (CC) for Each Color

The output channels are divided into three groups.

Group: 9-Bit (512-Step), Three Groups

Each group has a 512-step color brightness control

(CC). CC adjusts brightness control between colors.

•

LED Power Supply Voltage Up To 10 V

The maximum current value of all 48 channels can be

•

set by 8-step global brightness control (BC). BC

•

Constant Current Accuracy

adjusts brightness deviation between LED drivers.

–

Channel-to-Channel = ±1%(Typ), ±3%(Max)

GS, CC and BC data are accessible through a serial

interface port.
