Patent ID: 7994827

Claim:
A combination comprising: a power circuit comprising a power MOSFET and a load; a gate driver, an output terminal of the gate driver being connected to a gate terminal of the power MOSFET, the gate driver comprising: a first input terminal and a second input terminal, the first input terminal being connected to a first voltage source, the second input terminal being connected to a second voltage source; and a switching element for switching the output terminal between the first input terminal and second input terminal; a current sensor connected in the power circuit; and a trim circuit connected to the current sensor, the trim circuit adapted to adjust the magnitude of a voltage supplied by the second voltage source to a fixed value in response to an output signal from the current sensor, the trim circuit comprising a plurality of one-time programmable devices, each of the one-time programmable devices being responsively coupled to a programming circuit; wherein a first voltage provided by the first voltage source causes the power MOSFET to be in a fully on condition when delivered to the gate terminal and the fixed value of the voltage provided by the second voltage source causes the power MOSFET to be in a low-current condition when delivered to the gate terminal.
