Programmable gate voltage for on resistance control of power module

A system comprising:

• a first controller configured to generate a control signal;
• a power module;
• and
• a gate driver configured to drive the power module according to the control signal, the gate driver comprising:
• a driver configured to output a gate current to drive a power module;
• a buffer configured to buffer a reference voltage;
• and
• a second controller configured to:
• detect a fault condition;
• determine that the power module is in a first state;
• and
• in response to detection of the fault condition and determination that the power module is in the first state:
• change a gate voltage of the power module;
• determine the gate voltage has reached the reference voltage;
• and
• in response to determination that the gate voltage has reached the reference voltage:
• disable the driver to cause the driver to stop supplying the gate current to the power module;
• and
• enable the buffer to supply the reference voltage to the power module to transition the power module from the first state to a second state.

A method comprising:

• detecting, by a gate driver, a fault condition;
• determining, by the gate driver, a power module being driven by a driver is in a first state;
• and
• in response to detecting the fault condition and determining that the power module is in the first state:
• changing, by the gate driver, a gate voltage of the power module;
• determining, by the gate driver, the gate voltage has reached a reference voltage;
• and
• in response to determining the gate voltage has reached the reference voltage:
• disabling, by the gate driver, the driver to cause the driver to stop driving the power module;
• and
• enabling, by the gate driver, a buffer to supply the reference voltage to the power module to transition the power module from the first state to a second state.
