ABSTRACT:
A current detecting circuit includes a current detecting module includes a detecting resistor, a voltage transmitting module, and a current adjusting module including four field effect transistors, a transistor, and a operational amplifier. The first drain is connected to a power source via the detecting resistor. The first source is connected to a load. The second gate is connected to a signal control pin. The third gate is connected to the second drain. The fourth gate is connected to the third drain. The fourth source is connected to the power source via a first resistor and a collector. The first non-inverting input terminal is connected to the voltage transmitting module. An emitter is connected to the second non-inverting input terminal, and ground via a second resistor. The second non-inverting input terminal is connected to a cathode and the first standby power source.
