WS 2801 powerful output

  • Today I came across a Chinese control that incorporates the ws2801.
    If you look at the pattern, you will see that the resistor of 1.5k goes to + 12V.
    It is very interesting because the Data Sheet said that ws2801 maximum 7v.
    I do not know whether it was a mistake in the Data Sheet but control has been operating for godinuna days without problems.
    In this scheme better evokes gate feta


    How to control at 12V, + 12V to be of 8V to 10V. Everything depends on the molten WS2801
