Description

The TLC6C5748-Q1 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 TLC6C5748-Q1 has three error flags: LED open detection (LOD), LED short detection (LSD) and thermal shutdown (TSD). The error detection results can be read with a serial interface port.
