TLC5923DAPG4 datasheet by Texas Instruments

TLC5923DAPG4 Frequently Asked Questions (FAQs)

• What is the maximum current that can be sourced by each output?
  The TLC5923DAPG4 can source up to 25mA per output, but it's recommended to limit it to 15mA for reliable operation.
• How do I ensure that the device is properly powered up and initialized?
  Make sure to follow the power-up sequence specified in the datasheet, and ensure that the VCC pin is powered up before the VDD pin. Also, wait for at least 1ms after power-up before sending any data to the device.
• What is the maximum frequency of the clock signal that can be used with this device?
  The TLC5923DAPG4 can operate with clock frequencies up to 30MHz, but it's recommended to limit it to 10MHz for reliable operation.
• How do I handle the thermal shutdown feature of the device?
  The TLC5923DAPG4 has a built-in thermal shutdown feature that will shut down the device if it exceeds a certain temperature threshold. To handle this, ensure that the device is properly heat-sinked, and consider implementing a thermal monitoring and shutdown circuit in your design.
• What is the recommended layout and routing for the device's power and ground pins?
  It's recommended to use a solid ground plane and to route the power and ground pins as close together as possible to minimize inductance and noise. Also, ensure that the decoupling capacitors are placed as close to the device as possible.
