Several Protection features include current limiting with foldback, and thermal shutdown to prevent catas- trophic switch failure caused by increasing power dis- sipation when continuous heavy loads or short circuit occurs. And a built-in charge pump is used to drive the N-channel MOSFET that is free of parasitic body diode to eliminate any reversed current flow across the switch when it is powered off. G5250E/F/G/H, G5250I/J/K/L and G5250M/N/P has open- drain OC output reports over-current or over-temperature event and has typical 9ms deglitch timeout period.
