AW25072S/U is a universal high-performance LED driver IC designed to drive up to an 18×4 LED matrix.
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, de-ghosting, over-temperature protection (OTP), and thermal roll-off for robust system operation.
The device’s frame refresh rate can reach above 20 kHz, effectively preventing audible noise; the de-ghosting function is implemented via multi-gear negative voltage to protect LED beads from damage.
It comes in a QFN 4X4-32L package and operates at 2.7V to 5.5V between -40°C and +105°C.
