    50V, 50A H-Bridge IC needed

    It will be to drive coils / electromagnets so I was thinking that an IGBT would be better for 2 reasons. 1. They can have a high voltage rating and be more tolerant of voltage spikes. 2. They don't get as hot for a given current. The supply voltage to the load will be variable (although there...

    50V, 50A H-Bridge IC needed

    Wow, you made that diagram just for me! Thanks! I have a few more questions  ::) Will I need to change those resistor values if the supply voltage drops to 25V ? Just to confirm: The high site MOSFETs are ordinatry P-Type, and the low side ones are logic level N-Type ? They must not have...

    50V, 50A H-Bridge IC needed

    Yes, a schematic would be great thanks. Do you also know of a control IC that can be used to simplify the driving if it. e.g, prevents shoot through or other fault conditons?

    50V, 50A H-Bridge IC needed

    Hmm. I was hoping to avoid that as I'd need to make a high and low side driver too. Those IC's also have fault indicators and other useful stuff It only needs to go at 50Hz or less.

    50V, 50A H-Bridge IC needed

    Hi, I'm looking for an integrated H-Bridge IC like those used in motor control applications. I've seen the VNH3SP30-E (http://www.st.com/stonline/products/literature/ds/12688.pdf) but it is only rated for 36V. The current rating it has of 30A is just enough but ideally I would like something...
