TLC5922DAPR datasheet by Texas Instruments

TLC5922DAPR Frequently Asked Questions (FAQs)

• What is the maximum current that can be sourced or sunk by each output?
  The TLC5922DAPR can source up to 25mA and sink up to 50mA per output.
• How do I ensure that the device is properly powered up and initialized?
  The device requires a power-on reset (POR) circuit to ensure proper initialization. A 0.1uF capacitor between VCC and GND is recommended to filter out noise and ensure a clean power-up sequence.
• What is the recommended clock frequency for the TLC5922DAPR?
  The recommended clock frequency is between 100kHz to 25MHz. However, the device can operate up to 50MHz with reduced performance.
• How do I handle the thermal management of the TLC5922DAPR?
  The device has a thermal pad on the bottom of the package. Ensure good thermal conductivity by using a thermal interface material (TIM) and a heat sink if necessary. Keep the device junction temperature below 150°C to ensure reliability.
• What is the purpose of the OE (Output Enable) pin?
  The OE pin is used to enable or disable the output drivers. When OE is low, the outputs are enabled. When OE is high, the outputs are high-impedance (tri-stated).
