Description

 SGL8022W is a single-channel touch chip for LED lightness regulation. This chip can control the on/off state of LED light and regulate its lightness on a continuous range, which could be used on incandescent and halogen. As SGL8022W has an EFT value over ±2 KV, the touching sensitivity and response time of SGL8022W proves to be fine, even under the interference of mobile phones that exist in the near field. See the pin assignment and description of SGL8022W in SOP 8 package. The chip has a relatively wide range of input voltage, which could be chosen optionally within 2.4 to 5.5 Vdc.
