Hi All

How I can isolate the GND path also when any of the Power Supply failed or gets faulty, any solution for GND isolation.

    Hi Amit,

    By ground path isolation, do you mean to disconnect IC ground and power ground?

    This can be achieved with the configuration shown below.

    During power supply failure (power supply short), due to parasitic inductance, input might swing negative and damage the device. It is preferable to add a Schottky.
