    I have a application to drive a DC Servo Motor, the details are 50V
    Control Signals -
    1) Ei = -10V to +10V. (For speed and direction control such as
    a) -10V for High speed Clock Wise
    b) 0 V Motor Stop
    c) +10V for High speed Anti -Clock
    Wise Direction
    2) Enable - High for Enable Motor Rotation.
    Low for Stop Motor Instantly.

    We have a Tachogenerator as well as encoder to generate the feedback

    Please suggest a device at present i am using "Allegro 3959" and "3637
    for PWM", but i am finding it quite difficult.

    Thanks and regards...
