TLC5916IPWRG4 datasheet by Texas Instruments

TLC5916IPWRG4 Frequently Asked Questions (FAQs)

• What is the maximum current that can be sourced by each output?
  The TLC5916IPWRG4 can source up to 120mA per output, but it's recommended to limit it to 100mA to ensure reliable operation.
• How do I ensure that the LED outputs are turned off during power-up and power-down?
  To ensure that the LED outputs are turned off during power-up and power-down, connect the OE (Output Enable) pin to a logic low signal or tie it to GND. This will disable the outputs during power-up and power-down.
• What is the recommended value for the external resistor (Rext) connected to the IREF pin?
  The recommended value for the external resistor (Rext) connected to the IREF pin is 1kΩ to 10kΩ. This resistor sets the internal reference current, which in turn sets the maximum output current of the device.
• Can I use the TLC5916IPWRG4 to drive LEDs with different forward voltage drops?
  Yes, the TLC5916IPWRG4 can drive LEDs with different forward voltage drops. The device has an internal voltage regulator that allows it to operate with a wide range of LED forward voltage drops (up to 5.5V).
• How do I protect the TLC5916IPWRG4 from ESD and overvoltage?
  To protect the TLC5916IPWRG4 from ESD and overvoltage, use external ESD protection diodes (such as TVS diodes) and overvoltage protection devices (such as voltage regulators or zener diodes) on the power supply lines.
