TEXAS INSTRUMENTS  TLC5955DCA  发光二极管驱动器, 48输出, 线性, 3V-5.5V输入, 25MHz开关, 10V/31.9mA输出, HTSSOP-56

The 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.
