Key Featrues
24-Channel Constant-Current Sink Output: The TLC5947 supports 24 individual LED channels, each with a constant-current sink capability of up to 30 mA. This feature ensures uniform brightness across all LEDs, making it ideal for applications requiring precise and consistent lighting, such as LED displays and signage.
12-Bit PWM Grayscale Control: With 4096 steps of pulse-width modulation (PWM) control, the TLC5947 allows for highly precise dimming and color mixing. This enables smooth transitions and fine-tuning of LED brightness, enhancing visual quality in applications like stage lighting and decorative LED setups.
Thermal Shutdown (TSD) Function: The TLC5947 includes an automatic thermal shutdown feature that protects the device from overheating by turning off all output drivers. Once the temperature returns to normal, the drivers automatically restart, ensuring reliable operation and longevity in high-temperature environments.
4-MHz Internal Oscillator: The built-in 4-MHz oscillator eliminates the need for an external clock source, simplifying circuit design and reducing component count. This feature enhances efficiency and reduces overall system cost, making it suitable for compact and cost-sensitive applications.
Noise Reduction with Grouped Delay: The TLC5947 incorporates a 4-channel grouped delay mechanism to prevent inrush current, reducing electrical noise and improving system stability. This feature is particularly beneficial in applications where multiple LEDs are controlled simultaneously, such as in automotive lighting or large-scale LED installations.
