I'm using BUK768R1-100E mosfet in my application. I'm using this mosfet as a switching device to make and break the path for battery to load of 48V battery. for some time it is working fine all of sudden it getting shorted, if we try to turn off the mosfet its not getting turned off. (OR) it is working fine for sometime if i was making the gate pin low then it is getting shorted some times. Can anyone please help me regarding this issue..

here the red line is going to the BQ76200PWR nchannell mosfet driver
and from driver to the microcontroller gpio

Much more information is needed than just the brief description of the problem and a corner of the schematic. Can you provide the rest of the circuit and describe how the circuit works?
