TLC59116FIPWR datasheet by Texas Instruments

TLC59116FIPWR Frequently Asked Questions (FAQs)

• What is the maximum current rating for each output channel?
  The TLC59116FIPWR has a maximum current rating of 30mA per output channel, with a total device current rating of 120mA.
• How do I ensure that the device is properly powered and configured?
  To ensure proper operation, the device requires a 3.3V or 5V power supply, and the EN pin should be tied high to enable the device. Additionally, the SCL and SDA pins should be connected to a microcontroller or other I2C master device.
• What is the purpose of the REXT resistor, and how do I choose the correct value?
  The REXT resistor sets the current limit for each output channel. The recommended value for REXT is 1.24kΩ, but this can be adjusted based on the specific application requirements.
• How do I control the brightness of the LEDs connected to the TLC59116FIPWR?
  The TLC59116FIPWR uses pulse-width modulation (PWM) to control the brightness of the LEDs. The brightness can be adjusted by modifying the duty cycle of the PWM signal sent to the device.
• What is the maximum frequency for the I2C clock signal?
  The maximum frequency for the I2C clock signal is 400kHz, but it can be operated at lower frequencies if required by the application.
