The AW9109QNR is an LED driver device manufactured by Awinic. It is a 20-lead TQFN (Thin Quad Flat No-lead) package compliant with RoHS (Restriction of Hazardous Substances) requirements. It is a two-channel, low-noise, high-efficiency, linear LED driver that operates at 5.5V and can drive multiple strings of LEDs with an average current of up to 350mA. The AW9109QNR includes a boost circuit and current sensing resistors for controlling the brightness and protecting the LEDs from overvoltage, overheating, and short-circuit events. It also includes a dimming control interface that can be used to adjust the brightness of the LEDs.
