Low electromagnetic interference and switch loss motor driver

A method comprising:

• supplying, based on a gate drive current modulation profile, a first gate drive current level as a gate drive current when an output drive switch is operating within a first region;
• decreasing, based on the gate drive current modulation profile, the first gate drive current level to a second gate drive current level when the output drive switch transitions from the first region to operating within a Miller region;
• increasing, based on the gate drive current modulation profile, the second gate drive current level to a third gate drive current level within the Miller region;
• and
• setting, based on the gate drive current modulation profile, the gate drive current to a fourth gate drive current level when the output drive switch transitions from the Miller region to operating within a third region.

A motor driver comprising:

• a current control circuit configured to supply a gate drive current for an output drive switch coupled to an electric motor;
• and
• a hardware control logic coupled to the current control circuit, wherein the hardware control logic is configured to:
• determine a first gate drive current level as the gate drive current based on a determination that the output drive switch is operating within a first region;
• determine a second gate drive current level as the gate drive current that is less than the first gate drive current level based on a determination that the output drive switch transitions from the first region to operating within a Miller region;
• determine a third gate drive current level as the gate drive current that is greater than the second gate drive current level based on a determination that the output drive switch is operating within the Miller region;
• determine a fourth gate drive current level for the gate drive current based on a determination that the output drive switch transitions from the Miller region to operating within a third region;
• and
• transmit one or more instructions to the current control circuit that include the first gate drive current level, the second gate drive current level, the third gate drive current level, and the fourth gate drive current level.
