Hey guys,
Looking for a circuit presumably using a bunch of high current mosfets in order to create a " solid state relay" rated about 300a...
Trying to make a relay for my DIY spot welder. There are a bunch of circuits I found on Google but most of them are also implementing a timer circuit as well.
I just need to be able to have it trigger when 12v is applied. Instantly turn on when 12v is present and instantly turn off with 12v is not.
I understand I should probably use a bunch of fast switching power mosfets in series. Just not sure if I should be using p Channel or n Channel. And any other characteristics I should be looking for. Also something that is fairly common so it's easy to source and low cost
Any advice is greatly appreciated
Thank you
