Webbcompensate the positive temperature coefficient of the Rdson of the Mosfet. The above formula is only valid when the Mosfet is fully ON. Therefore during the turn on of the MOSFET, the time ‘Tblank on’ disables the vds protection until the Mosfet is fully On. Therefore a maximum resistor is specified for Rvds in the recommended section.
