A circuit element protection apparatus applied to a signal input terminal, the circuit element protection apparatus includes a slave processing unit, a main processing unit, a first soft start unit and a second soft start unit. The first soft start unit receives a signal from the signal input terminal, and is used for noise filtering on the signal and delayed a transmission of the signal to the slave processing unit. The second soft start unit receives the signal from the signal input terminal, and is used for noise filtering on the signal and delayed the transmission of the signal to the main processing unit. The present disclosure further includes a protection method for circuit elements.
