    Hello,

    I have this schematic that uses outdated electronics. My assignment is to renew this schematic but i want to keep everything after the mosfet's. The input is 5V PWM signal. Does anyone know a part of the schematic i can replace with an IC. An Ic that contains a MOSFET Driver with feedback would be perfect but can't seem to find one. I already know how this schematic works but i need help to update to modern electronics.
    (sorry for my english) schema.jpg

    Thanks in advance

    There is the pld Motorola MC33030 DC motor controller with F.B. that may do the job.
