Hi,
I'd like to learn about half bridge driver ICs that is being offered from International rectifier or similar ones IRF211XX series..
I ve got two N channel MOSFETs , high side MOSFET Drain connected to Vdd=28V ,its Source connected to Low side MOSFETs drain & Lowside MOSFET source is grounded.
The load is driven from the point at source of high side FET( where drain of lowside is connected).
I d really like to know how the IRF Ics drive the high side FET or how the VGs for high side is being supplied..?I think the High side FET gate should be supplied at least by a voltage =28V+Vgs threshold Isnt that right??Will these ICs generate that by themselves or shall i do something to set the Gate voltage?(wondering since the Vgs for different mosfets changes right?)
Can somebody explain me or help me to find a tutorial about the same..
Thanks & Regards
