Problems solved by technology

[0003] At present, the common high-side overcurrent detection circuit mainly collects the voltage at both ends of the sampling resistor through the operational amplifier, and converts it into a corresponding amplified voltage. It is also difficult to discharge and supply power. It needs to be able to withstand the peak and surge voltage of the high-side power supply. The system cost is high, the circuit structure is complex, and the fault detection performance is poor. The practical application is limited.
