Part number : SGL8022W, SGL8022
Functions : Single-channel DC LED control touch chip
Manufacturer : SiGma Micro
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.
A touch operation through TI corresponds to the output of SO, which could control lightness of LED. Four functional optionsare available, which are determined by input state of OPT1 and OPT2 before electrified:
(1) OPT1=1, OPT2=1: regulate lightness discretely without lightness-memory.
(2) OPT1=0, OPT2=1: regulate lightness continuously without lightness-memory.
(3) OPT1=1, OPT2=0: regulate lightness continuously with lightness-memory.
(4) OPT1=0, OPT2=0: regulate lightness on a three-sections mode.
