Validation of current levels delivered by a gate driver

A system for validating operation of a driver integrated circuit, the system comprising

• the driver integrated circuit, the driver integrated circuit including:
• an output node;
• a variable strength driver circuit coupled to the output node, the variable strength driver circuit being configured to provide a signal to the output node, the signal being provided using multiple set points in response to a change in state of an input signal, each set point corresponding to a different phase of a multi-phase transition of the signal;
• a timer circuit configured to provide a timer value at an end of a phase of the multi-phase transition;
• and
• a driver controller circuit configured to determine whether the signal is in a target signal range of the phase based on a comparison of the timer value at the end of the phase to a value based on a predetermined time limit of the phase and a predetermined value defining the target signal range of the phase.

A system for controlling a high-power drive device using a control signal, the system comprising:

• an output node;
• a variable strength driver circuit configured to provide a signal to the output node having a signal level based on a multi-bit digital control signal;
• and
• a control circuit configured to generate the multi-bit digital control signal corresponding to a target strength of the variable strength driver circuit and configured to generate an indication of an actual strength of the variable strength driver circuit corresponding to the multi-bit digital control signal based on a predetermined profile of a multi-phase transition of the signal, a first indication of a first parameter associated with the signal, a second indication of a second parameter associated with the signal, and a margin value of the predetermined profile, the margin value corresponding to the target strength of the variable strength driver circuit.
