1. A gate driver circuit having a drive signal input, a gate drive output, a power supply terminal, and a ground terminal, the gate driver circuit comprising:
a pull-up circuit having first and second terminals and first and second inputs, the first terminal coupled to the power supply terminal, the second terminal coupled to the gate drive output, the first input coupled to the drive signal input;
a pull-down circuit having first and second terminals first and second inputs, the first terminal of the pull-down circuit coupled to the ground terminal, the second terminal of the pull-down circuit coupled to the gate drive output, the first input of the pull-down circuit coupled to the drive signal input;
a level shifter circuit having an output coupled to the second input of the pull-up circuit and to the second input of the pull down circuit, and having an input; and
a drive strength control circuit having an output coupled to the input of the level shifter circuit.
