ASL5015EVBSLAV features the ASL5015SHN. The ASL5xxxyHz family is a fully-featured and flexible Matrix LED Controller (MLC). It provides a cost-effective design solution, specifically targeting advanced automotive exterior lighting applications. Smart PWM part numbers determine the PWM dimming duty cycle from information stored inside the MLC in the form of dimming polynomial curve coefficients. These coefficients are programmable by the customer according to the dimming profile they would like to see. The MLC uses these polynomial coefficients to calculate the PWM duty cycle to 12- bit resolution.
