description The utility model provides a protection circuit and an integrated circuit system, comprising a comparator, the positive input end of which is connected with a reference voltage, and the negative input end of which is connected with a load power supply circuit so as to input a circuit signal of the load power supply circuit to the negative input end of the comparator; the relay is arranged on the load power supply circuit and is connected in series with the load; a first triode, a second triode and an audible and visual alarm. According to the protection circuit and the integrated circuit system, the output end of the load power supply circuit is provided with the comparator, the comparator compares the power supply input voltage with the reference voltage and outputs the detection result to the relay, and the relay controls whether the power supply is output or not according to the detection result. Therefore, the circuit safety is protected, the equipment is prevented from being damaged, and the normal opera
