Zusammenfassung: | The invention relates to the technical field of high-side driving circuits and particularly discloses a discrete high-side driving circuit system, which comprises a control circuit, a driving circuitand a protection circuit, wherein the control circuit comprises a control signal input Vin, a voltage dividing resistor R1, a voltage dividing resistor R2, a current-limiting resistor R3 and a switching tube Q1; the driving circuit comprises a switching tube Q3 and an anti-reverse diode D1; and the protection circuit comprises a switching tube Q2, an EMC reducing resistor R4 and a current-limitingfeedback resistor R5. The circuit system is low in cost, can effectively solve the problems of current driving and PCB area, can effectively achieve the purpose of overcurrent protection/current-limiting protection, and is suitable for a driver with the medium current capability as the driving capability.
