Overview
The UAA2016PG, produced by ON Semiconductor, is a Zero Voltage Switch Power Controller designed to drive triacs using the Zero Voltage technique. This technique allows for RFI-free power regulation of resistive loads, making it particularly suitable for applications such as electrical heating systems, panel heaters, and irons. The device operates directly on the AC power line and features a built-in digital sawtooth waveform for proportional temperature regulation over a ±1°C band around the set point.
