I'm having trouble replacing a SPDT relay with a MOSFET circuit.
I have an SPDT relay that serves as an emergency brake of a small motor when the power goes off, shorting both motor inputs.
It's slow and I want to change with some MOSFET. I've read about depletion-mode MOSFETs, but they are hard to find for min. 20-30 A current.
I need this relay because when the power goes off, my 12 V motor goes on for some seconds.
