Description

AW25018S is a 18-channel high precision constant current LED driver. The device integrates both analog dimming and PWM dimming control modes. For analog dimming, each current sink can be adjusted with 256 steps. For PWM dimming, each LED can be adjusted with 4096 steps. The device supports Auto-Breath-Pattern and has a flexible and efficient lighting effect programming function, which can reduce the resource occupation of the main controller. The device supports advanced EMI reduction techniques such as programmable analog CS slew rate adjustment, CS-Group delay and spread spectrum clock modulation. It also includes features like independent open/short detection, over-temperature protection (OTP), and thermal roll-off for robust system operation.
