产品概述
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.
- 30mA Capability (constant-current sink)
- 12-bit (4096 steps) Greyscale PWM control
- ±2% (typical) Channel-to-channel, ±2% (typical) Device-to-device constant-current accuracy
- CMOS logic level I/O
- 30MHz Data transfer rate (standalone)
- 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
