The AS721x/AS722x are complete System-on-Chip (SoC) sensor-integrated IoT smart lighting managers for color-tunable white lighting applications. They also support daylight harvesting and color/lumen maintenance lighting applications. 0-10V control and network-enabled high-level command inputs are combined with industry-standard PWM and 0-10V outputs for direct control of LED power systems.
