Seeking help with designing a form " C " circuit using power FET.
Looking to us IRF1324S-7PPBF it is a 24V 0.00165 Rdon , using 8 to create the Form C relay , (2 set in parallel with 4 FET connect source to source gate to gate with all the Drain leads acting as the NO .COMMON . NC connection
Catch is need to use completely isolated gate drive to the two set , been looking at using Photovoltaic coupler such as TLP3904 /TLP3914/TLP3924 or TLP590B made by Toshiba , IR make a similar units to high price .
The probleme I need resolved is how to drive the big gate to source capacitance on those FET using the Photocoupler .
This is a real project that I have a order for to produce large quantity of Solid State relay Form " C" in the 100 to 300 AMPs region ( will be paralleling FET making situation worst ) working voltage is less than 2.0Volt switching .
Need to go from on to off and on in low microsecond or better .
Who ever is able to able should contact me there is money for a successful design, and good possibility of long term income from future sale.
Can be reached either by phone <SNIP> or on this site , I am presently in San Antonio TX
