DESCRIPTION

The TLC59482 is a 16-channel, constant-current sink driver. Each channel has an individually-adjustable,

pulse width modulation (PWM) grayscale (GS)

brightness control with 65,536 steps. All channels

have a 64-step global brightness control (BC). BC

adjusts brightness deviation with other LED drivers.

GS and BC data are accessible via a serial interface

port.
