i have a dc powered circuit from 15-to 50 A . 24-48v and maybe higher later !
the microcontroller issues at some fault a disconnect order . this should disconnect batteries by relay .
the question , can i replace the relay by a N-channel mosfet on the low side. ?? so the gnd is disconnected ? is this a good practice ?
i always read that GND should be secured and Vcc disconnected but why ??????? is it the same ?
thanks in advance
