The circuitis suitable for the DC power supply overcurrent protection, such as a variety of battery-powered applications. If the load current exceeds a preset value, the insurance will disconnect the DC electronic load. When you reset the circuit, you just need to cut the power off. The circuit has two connection points (A, B tag), the load can be connected to either side. Load current flows through the transistor T4, resistor R10 and R11. A, B terminals' voltage and load current are proportional to the majority of the voltage distribution in the resistor.
