General Description

IS31FL3236A is prised of 36 constant current channels each with independent PWM control, designed for driving LEDs, PWM frequency can be 3kHz or 22kHz.

The output current of each channel can be set at up to 38mA (Max.) by an external resistor and independently scaled by a factor of 1, 1/2, 1/3 and 1/4.

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.
  • I2C interface, automatic address increment function.
  • Four selectable I2C addresses.
  • SDB rising edge reset I2C module.
  • Internal reset register.
  • Modulate LED brightness with 256 steps PWM.
  • Each channel can be controlled independently.
  • Each channel can be scaled independently by 1, 1/2, 1/3 and 1/4.
  • PWM frequency selectable - 3kHz (default) - 22kHz.
  • -40°C to +85°C temperature range: - IS3.
