TLC5955RTQR Description
The TLC5955 is a 48-channel, constant-current sink driver. Each channel has an
individually-adjustable, pulse width modulation (PWM), grayscale (GS)
brightness control with 65,536 steps and 128 steps of constant-current dot
correction (DC). DC adjusts brightness deviation between channels. All
channels have a 128-step global brightness control (BC). BC adjusts brightness
deviation between the R, G, B color group. The eight-step maximum current
control (MC) selects the maximum output current range for all channels of each
color group. GS, DC, BC, and MC data are accessible with a serial interface
port.
The TLC5955 has two error flags: LED open detection (LOD) and LED short
detection (LSD). The error detection results can be read with a serial
interface port.
