LED7708 datasheet by STMicroelectronics

LED7708 Frequently Asked Questions (FAQs)

• What is the maximum current that can be sunk by each channel?
  The maximum current that can be sunk by each channel is 100mA, but it's recommended to limit it to 80mA for reliable operation.
• How do I ensure that the LED7708 is properly powered?
  The LED7708 requires a 3.3V or 5V power supply, and it's recommended to use a decoupling capacitor of at least 10uF between VCC and GND to ensure stable operation.
• What is the purpose of the EN pin?
  The EN (Enable) pin is used to enable or disable the entire device. When EN is low, the device is in shutdown mode and consumes minimal power.
• How do I program the LED7708?
  The LED7708 is programmed using a serial interface (SPI or I2C) and requires a microcontroller or other external controller to send commands and data to the device.
• What is the maximum frequency of the clock signal?
  The maximum frequency of the clock signal is 10MHz, but it's recommended to use a clock frequency of 1MHz or less for reliable operation.
