Hi Gents,
I am an electronics tech (not a designer) and have inherited a product that seems to suffer from problems.
the circuit has a TL494 that drivers 2 IR 2110s into a H bridge.
I have cleaned up lots of the switching noise -using gate resisitors has done lots but I still seem to kill the IR2100s and the H bridge FETS.
My supply line seems to be very solid without much noise or any sag.
The failures are always dead at start up - the FET gate is short to source and also the IR 2110 is damaged.
Any idea or help appreiacted!!!
go gentle
cheers
Andy
