TLC5927IPWPR datasheet by Texas Instruments

TLC5927IPWPR Frequently Asked Questions (FAQs)

• What is the maximum current that can be sourced or sunk by each output?
  The TLC5927IPWPR 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 TLC5927IPWPR?
  The recommended clock frequency is between 10kHz to 25MHz. However, the device can operate up to 40MHz with reduced performance.
• How do I handle the thermal management of the TLC5927IPWPR?
  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 junction temperature below 150°C to ensure reliable operation.
• What is the purpose of the EN pin, and how do I use it?
  The EN (enable) pin is used to enable or disable the output drivers. When EN is low, the outputs are disabled and in a high-impedance state. When EN is high, the outputs are enabled and can drive the load.
