The HC6022 is an integrated
200mΩ Power switch for self-powered and bus-powered Universal Series Bus (USB) applications. Its low quiescent supply current(50uA)and small package (SOT-23-5) is particularly suitable in battery-powered portable equipment.
Several protection functions include soft start to
limit inrush current during plug-in, current limiting
at 0.8A (V IN =3.0V), and thermal shutdown to
protect damage under over current conditions.
