TLC5916IDRG4 datasheet by Texas Instruments

TLC5916IDRG4 Frequently Asked Questions (FAQs)

• What is the maximum current that can be sourced or sunk by each output?
  The TLC5916IDRG4 can source up to 30mA and sink up to 50mA per output, making it suitable for driving LEDs, relays, and other loads.
• How do I ensure that the outputs are turned off during power-up and power-down?
  The TLC5916IDRG4 has a built-in power-on reset (POR) circuit that ensures all outputs are turned off during power-up and power-down. Additionally, the device has an undervoltage lockout (UVLO) feature that prevents the device from operating when the supply voltage is below 2.5V.
• Can I use the TLC5916IDRG4 to drive inductive loads like relays and solenoids?
  Yes, the TLC5916IDRG4 can be used to drive inductive loads like relays and solenoids. However, it's essential to use a flyback diode or a snubber circuit to protect the device from back-EMF generated by the inductive load.
• How do I program the TLC5916IDRG4 to operate in 7-bit or 8-bit mode?
  The TLC5916IDRG4 can be programmed to operate in 7-bit or 8-bit mode by setting the MODE pin high or low, respectively. In 7-bit mode, the device can address up to 128 LEDs, while in 8-bit mode, it can address up to 256 LEDs.
• What is the maximum frequency of the clock signal that can be used to drive the TLC5916IDRG4?
  The TLC5916IDRG4 can operate with clock frequencies up to 30MHz, making it suitable for high-speed applications like video displays and LED lighting systems.
