For half-bridge configurations specifically, there is also the risk of cross-conduction, or shoot-through, of the two power switches. Some half-bridge drivers have a logic-based feature to prevent this called interlock. Interlock logic prevents the high- and low-side outputs from being on at the same time by turning off the outputs whenever both inputs are simultaneously high. This situation can occur when parasitic layout inductance cause ringing on the input signal. Gate drivers can also integrate a minimum dead time feature to avoid cross-conduction. This is often a fixed value, though some drivers have an additional pin to program the dead time duration for greater design flexibility.
