The ISL6884 brightness controller provides an I2C interface for dimming control, enable, status, and brightness balance. The duty cycle of all 8 DPWM outputs is adjusted with a Master Brightness Control register. The duty cycle of each of the 8 DPWM outputs can be offset from the master brightness to adjust for uniform brightness. The PWM dimming frequency can be set by an internal, adjustable oscillator or synchronized to an external source to minimize interference with video. ISL6884's slave address is:
