TLC5952DAPR datasheet by Texas Instruments

TLC5952DAPR Frequently Asked Questions (FAQs)

• What is the maximum frequency of the clock input?
  The maximum frequency of the clock input is 25 MHz, but it's recommended to keep it below 10 MHz for reliable operation.
• How do I handle the thermal shutdown feature?
  The TLC5952DAPR has a built-in thermal shutdown feature that turns off the device when it overheats. To handle this, you can monitor the TSD pin, which goes low when the device is in thermal shutdown. You can then take corrective action, such as reducing the current or turning off the device.
• What is the recommended layout for the device?
  For optimal performance, it's recommended to follow a star-shaped layout for the power and ground connections, with the device at the center. This helps to reduce noise and improve thermal performance.
• How do I program the grayscale data?
  The TLC5952DAPR uses a 5-bit grayscale data format, where each bit corresponds to a specific brightness level. You can program the grayscale data using the SDI pin, which accepts serial data. Make sure to follow the correct protocol and timing for data transmission.
• What is the purpose of the OE pin?
  The OE (Output Enable) pin is used to enable or disable the output of the device. When OE is low, the output is enabled, and when OE is high, the output is disabled. This pin can be used to blank the output during power-up or power-down sequences.
