G
* IC1 initial working
circuit
* It works at Initial
Voltage of 15V,
then 12V.
* It is reset to initial
state under 10V.

Point Oscilloscope Measurement Remark
H
* Protection of power
circuit
* Second side works
abnormally such as
short, etc.
* It blocks power to
protect power circuit
when Vcc is
sensed under 10V.
