Abstract

The invention discloses a circuit protection device which is connected with a test device and a device under test. The circuit protection device comprises a first interface which is electrically connected with the device under test, wherein a first level state is acquired; a protection circuit with one end thereof electrically connected with the first interface, wherein the first level state is acquired and the on / off state of the protection circuit is controlled according to the first level state; and a second interface with one end thereof electrically connected with the other end of the protection circuit, and the other end of second interface electrically connected with the test device. By using the circuit protection device, the first level state of the device under test is acquired through the first interface and the on / off state of the protection circuit is controlled according to the first level state. Therefore the protection for the test device is obtained.
