SC3071X touch step dimming light circuit

SC3071X is also a product of Hangzhou Shi3÷ Microelectronics Co., Ltd. It has one more mode
selection than SC3071, so SC3071X
can not only control the light
in four levels: low light, medium light, bright light and extinguishing
, but also "select
bright" . It has a fire switch type 2-speed control
, and its circuit address is 1 45.
  SC3071X series (YMOS
large-scale integrated circuit , using
Die black paste soft packaging, has a total of
10 pins, and
the functions of each pin are: ① pin ()se , is the oscillation end connected to an external oscillating motor; 0 pin n is the AC signal synchronization input end; 0
pin 60, SOHz, is the AC frequency cylinder selection end. When the frequency is JJ 50 FIz, the N end is left floating; ④ Pin V.,,
the positive terminal of the power supply; ⑤ pin SI., contact signal input terminal; ⑥ pin VI, is the voltage control terminal; 0 pin TI:ST, is the test
terminal, for processing; ⑧ pin L) I' T, mode selection terminal, this terminal is left floating for 4 mixing ratio, connected to ~', . for closed operation
mode ; ⑨ pin Vs., i L source terminal; ⑩ pin TR1. Pulse output terminal, triggers the product III tube VTH.
    In the picture, S is the working mode selection switch. When S is turned off and M is touched repeatedly, the light brightness
will change in a four-way cycle: low light, medium light, brightest, off... When Di touches, the lamp is the same as the fu. When touching the second time,
the lamp goes out, which means it is on.
