Hey guys running a DC motor off 9.6v bat, using bd681g darlington transistor as a switch off a 555timer IC.
First question is whats the voltage i use to calculate the saturation current for the Base? e.g. do i use 9V or some IC related voltage (transistor max current is 4A)? and if a transistor isnt saturated does it mean that its providing more resistance leading to heat??????
