    How to match this gate driver to this mosfet?

    Hi, I've selected this MOSFET for a motor control application [picture attached]: IRF200P222 Datasheet: https://goo.gl/nt9Nou I'm going to use low side configuration. I've chosen the 1EDN751x gate driver which has two possible ways of using it. I attach them. What is the best way to use it...

    Typical Application Connection IRAMX20UP60A

    Hello, Looking into the datasheet of the IRAMX20UP60A, I found a typical application connection which I am trying to understand. I attach a picture of the application circuit. The part inside the black square is what I don't understand. As far as I understand, if a low signal goes into the base...

    Variable Frequency Op-Amp Astable

    I am trying to design an oscillator which ranges from a very low value (near 0) to 2kHz. I found an useful lead which I attach below. However, I am not familiar enough with this circuit so I am not sure about how to calculate and modify the range of this circuit. I would appreciate any leads...
