Thanks @dick_freebird .
Yes I am going to do this. I am a bit concerned about blowing the input of the scope considering how the circuit blows up TVS diodes so easily. I will take a look at the output of the power supply first and see what is going on there where the voltage levels should be...
It is this so called "rugged FET" rated for avalanche situations so I am a bit surprised it's failing in this scenario.
If it isn't overvoltage why do you think the TVS would fail? Seems to me it must be absorbing energy for it to become damaged and the only way I can see it conducting is if...
I am trying to protect a FET from an Ldi/dt voltage spike and would really appreciate any advice. I am trying to protect in the event of a short circuited load. When I short out the load ie. connect Lead A to Lead B in the diagram below the FET blows, not from over current but over voltage. The...
Thanks so much for the help.
Thanks, so I will go for current detection using a resistor. In my initial post I suggested using a high side current sensing IC . Is there any benefit to measuring current on the high side vs between Source and Ground other than I guess it will raise my FET VGS...
I am in the beginning stages of designing a circuit that will protect a low side FET when it sees a short circuited load. Currently I am contemplating using this FET and this driver . The FET is being driven with a PWM frequency of approx. 15 KHz . My load is some LED lights at 24 Volts and...
