IS31FL3731-SALS2-TR Frequently Asked Questions (FAQs)

  • The recommended PCB layout for optimal thermal performance involves placing thermal vias under the IC, using a solid ground plane, and keeping the PCB layer stack-up symmetrical. Additionally, it's recommended to use a thermal pad on the bottom of the IC and connect it to a solid copper area on the PCB.
  • To ensure reliable communication with the IS31FL3731-SALS2-TR over I2C, make sure to use a pull-up resistor on the SCL and SDA lines, keep the clock frequency within the recommended range (100 kHz to 400 kHz), and use a repeater or buffer if the bus is long or has multiple devices.
  • The maximum current that can be sourced by the LED drivers in the IS31FL3731-SALS2-TR is 30mA per channel. However, the total current sourced by all channels should not exceed 150mA to ensure reliable operation and prevent overheating.
  • To implement PWM dimming with the IS31FL3731-SALS2-TR, use the device's built-in PWM generator and set the PWM frequency and duty cycle using the I2C interface. The PWM output can then be used to drive the LEDs. Make sure to follow the recommended PWM frequency range (100 Hz to 1 kHz) for optimal performance.
  • The recommended power-up sequence for the IS31FL3731-SALS2-TR is to first apply the power supply voltage (VDD) and then the logic supply voltage (VCC). This ensures that the internal voltage regulators are properly initialized and the device operates correctly.
