TLC5920DLG4 Frequently Asked Questions (FAQs)

  • The TLC5920DLG4 can source up to 25mA and sink up to 50mA per output, making it suitable for driving LEDs, relays, and other loads.
  • To ensure that the outputs are in a high-impedance state during power-up or power-down, connect the OE (Output Enable) pin to VCC through a pull-up resistor. This will keep the outputs in a high-impedance state until the device is fully powered up and the OE pin is actively driven low.
  • The recommended clock frequency for the TLC5920DLG4 is between 100 kHz and 25 MHz. However, the device can operate at frequencies up to 40 MHz, but with reduced noise immunity and increased power consumption.
  • To handle thermal dissipation, ensure that the device is mounted on a PCB with a sufficient thermal pad and that the PCB is designed to dissipate heat effectively. Additionally, consider using a heat sink or thermal interface material to reduce the thermal resistance between the device and the ambient environment.
  • Yes, the TLC5920DLG4 can be used to drive inductive loads, such as relays and solenoids, but it's essential to add a flyback diode to protect the device from back-EMF. Additionally, ensure that the output current and voltage ratings are not exceeded, and consider adding a snubber circuit to reduce electromagnetic interference (EMI).
