We found this CMOS circuit for excitation of a relay in an old documentation. The transistor is a general-purpose high voltage as used in the power supply.
Although this version of electric fence is quite sophisticated due to the number of components it uses and...
Using the M1575 this switching converter was found in National Semiconductor documentation from...
This circuit was obtained from a 1985 Electronic Desing. The circuit uses a Darlington which may be...
