TLC5955DCAR

具有点校正、亮度控制和开路/短路检测功能的 48 通道、16 位 PWM LED 驱动器 56-HTSSOP -40 to 85

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.
