TLC5923RHBRG4 Frequently Asked Questions (FAQs)

  • The TLC5923RHBRG4 can source up to 25mA and sink up to 50mA per output, making it suitable for driving LEDs, relays, and other loads.
  • Make sure to connect VCC to a 3.3V or 5V power supply, and GND to a common ground. Also, ensure that the OE (Output Enable) pin is tied low to enable the outputs, and the RST (Reset) pin is tied high to prevent device reset.
  • The REXT resistor sets the output current of the device. Choose a value between 1kΩ and 10kΩ to set the output current between 2.5mA and 25mA. A lower REXT value results in a higher output current.
  • Yes, but be aware that inductive loads can cause voltage spikes when turned off. Add a freewheeling diode or a snubber circuit to protect the device from these voltage spikes.
  • The TLC5923RHBRG4 has a 5V-tolerant input, so it can be directly connected to most microcontrollers or digital logic. Use a serial interface (e.g., SPI or I2C) to send data to the device, and ensure that the clock frequency does not exceed 25MHz.
