In a programmable current sink I plan to use a power mosfet. This has a significant gate capacity (several nF) which cannot be driven by the opamp directly – at least not in a speedy manner, so I want to put a gate-driver in between.
The circuit looks like ´this in broad terms.
The gate driver drawn is just an illustrative example.
It is easy to find gate drivers, but the vast majority are for digital application – i.e. they typically have hysteresis in the input. This is not god for an analog application like this where precision and speed are key elements.
I can of course build my own gate drive from discrete components similar to the illustration, but I would expect this to be a problem already solved in an integrated manner.
Can you help me determine if TI has an analog gate driver solution?
Thanks for any advice you may have.
