Produktbeschreibung

The TLC5955DCA is a 48-channel 16-bit PWM constant-current LED Sink Driver with open/short detection. Each channel has an individually-adjustable, pulse width modulation (PWM), grayscale (GS) brightness control with 65536 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 colour group. The eight-step maximum current control (MC) selects the maximum output current range for all channels of each colour group. GS, DC, BC and MC data are accessible with a serial interface port. It has two error flags of LED open detection (LOD) and LED short detection (LSD). The error detection results can be read with a serial interface port.
