Abstract
In one embodiment, a power MOSFET driver uses two different voltages for the operating voltage of the two output drivers of the power MOSFET driver.
Claims20
A power MOSFET driver comprising:
- a first transistor driver coupled to operate from a first voltage having a first value and form a first drive signal operable to drive a first MOS transistor;
- and
- a second transistor driver coupled to operate from a second voltage having a second value and form a second drive signal operable to drive a second MOS transistor.
A method of forming a power MOSFET driver comprising:
- configuring a first transistor driver of the power MOSFET driver to form a first drive signal having an output voltage value corresponding to a first voltage value of a first power supply;
- and
- configuring a second transistor driver of the power MOSFET driver to form a second drive signal having an output voltage value corresponding to a second voltage value of a second power supply that is less than the first voltage value.
A method of operating a power MOSFET driver comprising:
- operating a first transistor driver of the power MOSFET driver from a first operating voltage value;
- and
- operating a second transistor driver of the power MOSFET driver from a second operating voltage value.
