The TLC5947DAP from Texas Instruments is a versatile 24-channel, constant-current sink LED driver. Each channel offers 12-bit (4096 steps) pulse-width modulated (PWM) grayscale control, allowing for precise brightness adjustment.
This device supports a constant-current sink capability of up to 30mA per channel. The LED power-supply voltage can range up to 30V, while the VCC supply voltage is between 3.0V and 5.5V. It features a 4MHz internal oscillator and a data transfer rate of up to 30MHz in standalone mode.
Designed for applications such as static LED displays, message boards, and amusement illumination, the TLC5947DAP is housed in a 32-HTSSOP surface mount package. Its constant-current accuracy is typically ±2% channel-to-channel and device-to-device. The driver also includes a thermal shutdown (TSD) function for protection against over-temperature conditions.
Key features include CMOS logic level I/O, auto display repeat functionality, and noise reduction through a 4-channel grouped delay. The operating temperature range is -40°C to 85°C.
