Hello,
When P12V_STBY of IC power insert , pin2 of TRIG_N and pin3 of OUT go high together , this part had be trigger , it seem LM555CMX is to sensitive , pin2 of TRIG_N don't ready but IC had ready cause pin3 of Out pin to trigger, Do you have any idea whether we adjust Res or cap to avoid too senstive? Thank you.
