The TLC5947DAP is a 24-channel, 12-bit PWM Constant-current Sink LED Driver with internal oscillator. Each channel is individually adjustable with 4096 pulse-width modulated (PWM) steps. PWM control is repeated automatically with the programmed greyscale (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 TLC5947DAP 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.
15MHz Data transfer rate (cascaded devices, SCLK duty = 50%)
Shift out data changes with falling edge to avoid data shift errors
Auto display repeat
4MHz Internal oscillator
Automatic shutdown at over-temperature conditions, restart under normal temperature thermal shutdown
4-channel Grouped delay to prevent inrush current noise reduction
Green product and no Sb/Br
Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
