SGL8012W is a single-channel touch chip for dimming lights. This chip can achieve touch on/off and infinite dimming of lights, and is suitable for incandescent lights and halogen lights.
The SGL8012W is a single‑channel touch chip designed for lamp brightness adjustment. It supports touch on/off and stepless dimming for incandescent or halogen lamps, with features such as wide voltage range, low component count, and strong immunity to power and phone interference.
The device is supplied in DIP‑8 and SOP‑8 packages with detailed pin assignments, mechanical dimensions, and an example application circuit. Electrical parameters include a typical 5.1 V operating voltage, 700 µA current consumption, and defined high/low level thresholds. A revision history documents updates up to version 1.3. This manual is written in Chinese.
