Abstract
A method of controlling a slew rate of a MOSFET connected to a battery for supplying an electrical current to an electrical load is provided. A state transition of the MOSFET is provided and a drain-source voltage of the MOSFET is monitored. A variable current is provided through a gate of the MOSFET. A constant current is provided through the gate of the MOSFET, when the drain-source voltage of the MOSFET satisfies a predefined condition that is a function of a battery voltage.
