description	The utility model relates to the technical field of high-side circuit protection, and particularly provides a high-side output protection circuit with current monitoring, which comprises a main input end Vin, a main output end Vout and a control signal DO, the high-side output protection circuit further comprises a high-side output driving circuit, a current sampling and amplifying circuit and a hysteresis comparison circuit. According to the utility model, through the current sampling amplification circuit and the hysteresis comparison circuit which are matched with the high-side output driving circuit for application, when the output current is greater than a set value, the output is controlled to be switched off, so that the functions of high-side output circuit protection and current monitoring are realized; the hysteresis comparison circuit has a turn-off holding function, and when the current of the circuit exceeds a set value, the PMOS is kept in a turn-off state and is not controlled by input, so that
