    Hi all,

    I have a question about FET Drivers

    The kind of FET drivers that I am interested are used for driving
    MOSFETs used for low voltage (<2V) high current (30A/phase)
    environments at switching frequency from 300KHz to 1MHz. A typical FET
    driver used widely in our applications is an ISL6594 and the LTC4441.,0,ISL6594A,0.html

    1. What are some of the common schemes/circuits used by FET driver
    manufacturers? I am especially interested in protection against:
    a) Shootthrough
    b) Over voltage
    c) Boot-strap diode breakdown.

    2. Where do I get information online about these common techniques.
    While the unitrode lectures are very useful in gaining an
    understanding of basics, it is a little outdated in terms of what is
    available in the market.

    Thanks in advance.
