Gate driver system for detecting a short circuit condition

A driver system configured to drive a motor, the driver system comprising:

• a first half-bridge circuit comprising a first high-side transistor and a first low-side transistor coupled at a first output node, wherein the first high-side transistor and the first low-side transistor are configured to cooperatively generate a first load current at the first output node for driving the motor;
• a second half-bridge circuit comprising a second high-side transistor and a second low-side transistor coupled at a second output node, wherein the second high-side transistor and the second low-side transistor are configured to cooperatively generate a second load current at the second output node for driving the motor;
• a first voltage charging device coupled to a first power supply and to the first output node;
• a second voltage charging device coupled to a second power supply and to the second output node;
• and
• a diagnostic circuit configured to monitor a first charging voltage of the first voltage charging device and a second charging voltage of the second voltage charging device, detect a first charging time at which the first charging voltage is charged to a first threshold voltage, detect a second charging time at which the second charging voltage is charged to a second threshold voltage, and detect a short circuit condition on a condition that a time difference between the first charging time and the second charging time is less than a time difference threshold.
