Connect the collector and emitter of the first transistor,
A bridge is configured by a second and third resistor and a load, and the base and emitter of a third transistor are connected between the output of the bridge; and the collector of the third transistor and the emitter of the second transistor. By connecting the bridge to the base, when the bridge is overloaded, it becomes unbalanced, and the second transistor is turned on, thereby shorting the penis and emitter of the first transistor. amplifier.
