Part Description
The TLC5947 is a 24-channel, constant-current sink LED driver. Each channel is individually adjustable with 4096 pulse-width modulated (PWM) steps. PWM control is repeated automatically with the programmed grayscale (GS) data. GS data are written via a serial interface port. The current value of all 24 channels is set by a single external resistor. The TLC5947 has a thermal shutdown (TSD) function that turns off all output drivers during an overtemperature condition. All of the output drivers automatically restart when the temperature returns to normal conditions.
