Power Switch ICs for Power Distribution are highly integrated semiconductor switches designed to safely control and route electrical power rails on a PCB. Combining low-on-resistance (RDSon) N-channel or P-channel power MOSFETs with charge pumps, control logic, and comprehensive diagnostic outputs on a single die, these load switches function as intelligent electronic fuses, protecting upstream power supplies from short circuits and overload events.
These load switches are widely used to manage power rails in smartphones, protect USB VBUS lines, and coordinate distributed power buses in automotive ECUs and servers. Critical specifications include operating voltage range, continuous current rating (A), programmable current limit accuracy, on-resistance, reverse current blocking, and fault flag status outputs. Automotive variants require AEC-Q100 qualification.
