TLC5946PW Frequently Asked Questions (FAQ)
-
The maximum frequency of the clock input is 30 MHz, but it's recommended to keep it below 20 MHz for reliable operation.
-
The grayscale signal should be updated during the blanking period, and the blanking signal should be asserted after the grayscale signal is updated. This ensures that the LEDs are updated correctly and avoids any flickering or artifacts.
-
The OUTGRP pin is used to group multiple TLC5946PW devices together to control a larger number of LEDs. It allows the devices to be cascaded and synchronized, enabling the control of up to 48 LEDs with a single device.
-
The TLC5946PW has built-in thermal shutdown and overcurrent protection. If the device overheats or detects an overcurrent condition, it will shut down and the TSD pin will be asserted low. To handle this, you can monitor the TSD pin and take corrective action, such as reducing the current or turning off the device.
-
To minimize noise and ensure reliable operation, it's recommended to keep the power and ground traces separate, use a solid ground plane, and keep the clock and data lines short and shielded. Additionally, place decoupling capacitors close to the device and use a low-ESR capacitor for the VCC pin.
