Discrete MOSFET driver, limiting voltage
Well, your choices are limited.  You could use a TVS diode from gate to source, and a resistor in series with the gate to clamp Vgs.  Of course that will slow down the switching and you'll have higher switching losses.  Same goes with the supply voltage- The TL5001 only draws a couple of mA, so a shunt regulator could work at the cost of more power dissipation.
