General Description

IS32FL3209 is comprised of 18 constant current channels each with independent PWM control, designed for driving LEDs, PWM frequency can be 29kHz (default) or 4kHz.

The output current of each channel can be set at up to 78mA (Max.) by an external resistor and independently scaled by a factor of 1, 23/24, 22/24, 21/22, 20/24, 19/24, 18/24, 16/24, 14/24, 12/24, 11/24, 9/24 and 7/24.

The average LED current of each channel can be changed in 256 steps by changing the PWM duty cycle through an I2C interface.

Key Features

  • 2.7V to 5.5V supply.
  • Each channel output current up to 78mA.
  • I2C interface, automatic address increment function.
  • Four selectable I2C addresses.
  • Internal reset register.
  • Modulate LED brightness with 256 steps PWM.
  • Each channel can be controlled independently.
  • Each channel can be scaled independently by 1, 23/24, 22/24, 21/22, 20/24, 19/24, 18/24, 16/24, 14/24, 12/24, 11/24, 9/24 and 7/24.
  • PWM frequency selectable -.
