Zusammenfassung:An integrated circuit, IC (100) includes: an input terminal; an output terminal; a first reference voltage terminal (131) and a second reference voltage terminal (135); a high-side power switch (127) coupled between the first reference voltage terminal (131) and the output terminal; a low-side power switch (129) coupled between the output terminal and the second reference voltage terminal (135); a first combinational logic (105) and a second combination logic (107) that are coupled to the input terminal; a first driver (111) coupled between the first combinational logic (105) and the high-side power switch; a second driver (113) coupled between the second combinational logic (107) and the low-side power switch; and first comparators (141A/141B) coupled to the second combinational logic (107), where the first comparators are configured to compare a voltage difference between load path terminals of the high-side power switch (127) with a first threshold and a second threshold.
