Shoot-Through Suppression Time Delay is provided to prevent directly connected high- and low-side MOSFETs from being on
simultaneously.
Current Limit Time Delay: The internal comparator places the device in the current limit mode when the comparator output goes LOW
and sets an internal logic bit. This takes a finite amount of time and is stated as the Current Limit Time Delay.
