Abstract
A gate driver circuit includes a high-side region that operates in a first voltage domain; a low-side region that operates in a second voltage domain lower than the first voltage domain; a gate driver configured to drive a power switch between an on-state and an off-state; at least one capacitor cross-coupled to the high-side region and the low-side region; a sensing circuit coupled to the at least one capacitor and configured to provide a sense value representative of a voltage transient of the power switch; a comparator circuit configured to compare the sense value to a threshold, and further configured to generate a comparison result based on whether the sense value satisfies the threshold; and a short circuit detector configured to detect a short circuit event based on the on-state of the power switch being detected and based on the comparison result indicating that the sense value satisfies the threshold.
