TLC5947 12-Bit 24-Channel LED Driver PWM Module w/ Internal Oscillator

Product Introduction: 1.Data Transfer Rate:30MHz (typical) 2.Accuracy:+/-2% (typical) 3.Special Features:internal GS Clock;thermal Shutdown 4.Rating:catalog 5.Operating Temperature Range:-40~85 celsius Features: 1.24 Channels,Constant-Current Sink Output 2.30mA Capability (Constant-Current Sink) 3.12-Bit (4096 Steps) PWM Grayscale Control 4.LED Power-Supply Voltage Up to 30V 5.VCC=3.0V to 5.5V 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 over-temperature condition. All of the output drivers automatically restart when the temperature returns to normal conditions.
