TLC5947RHBT General 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.
Key Features
- 24 Channels, Constant-Current Sink Output
- 30-mA Capability (Constant-Current Sink)
- 12-Bit (4096 Steps) PWM Grayscale Control
- LED Power-Supply Voltage Up to 30 V
- VCC = 3.0 V to 5.5 V
- Constant-Current Accuracy:
- Channel-to-Channel = ±2% (Typical)
- Device-to-Device = ±2% (Typical)
- CMOS Logic Level I/O
- 30-MHz Data Transfer Rate (Standalone)
- 15-MHz Data Transfer Rate (Cascaded Devices,
SCLK Duty = 50%) - Shift Out Data Changes With Falling Edge to
Avoid Data Shift Errors - Auto Display Repeat
- 4-MHz Internal Oscillator
- Thermal Shutdown (TSD):
- Automatic Shutdown at OverTemperature Conditions
- Restart Under Normal Temperature
- Noise Reduction:
- 4-Channel Grouped Delay to Prevent Inrush Current
- Operating Temperature: –40°C to 85°C
